Best Tips For Becoming A Better JavaScript Coder

Related Articles

Are you looking to improve your JavaScript skills – or just wondering what it takes to be a better JavaScript developer? If you want to improve your JavaScript skills, this is a great professional choice. JavaScript is the most common language for developers, mainly because it is the browser language. If an application uses the Internet, it uses JavaScript. And if you use JavaScript – and you’re good at it – you can really recharge your turbo career.

You should try to improve your JavaScript skills not only for professional reasons, but also because you enjoy working with the language. If you’re something like me (I started with Ruby), you might find JavaScript intimidating at first – or even contemptuous of it. Fortunately, the more I use JavaScript, the more I like it.

1. Grab the basics more thoroughly

I’ll start with a basic concept and a statement you’ve heard since you were young. Learn the basics and put them into practice. Many times, you will start logic with coding, but forget that there is already a built-in function for it, like array cutting. When you run JavaScript code, you may get an error, and as a result, many additional features stop working. It can be caused by a single colon or inverted commas. These things occur as a result of a lack of understanding of the elements. Many times in a single program, a simple loop like for, which, or do while is employed. Loops are one of the most basic concepts in programming. If you are not clear with the loop and the rest of the basics, it is really very difficult to code and even get a chance to get hired for a company. It is very important to brush up on your basics because they give you a strong foundation on which to build the complex logic of a solution and a strong reputation.

Use functions to configure different modules, even if they are small

Functional approach programming is a great way to go. Why? It separates your program into modules that work together but are still separate from each other. Let me give you an example to help you understand. The base square of the numbers can be calculated using a function. To do this, you need to square the integers, calculate their mean, and then calculate the square root of the mean. There are three steps in the process. As a result, we can run three functions. But, as you can see, all of these functions are interrelated. The output of one passes to another and then we get the final answer. Now, suppose instead of three functions, you use only one function to calculate RMS using different variables. As you can see, the final answer is wrong. You will have a really hard time now, checking where what went wrong in such a large function. Instead, three small functions will help you analyze quickly. Thus, use functions to define different modules of the code, even if the functions are small. This tip will work like a charm to help you become a JavaScript master.

Construction of modular, special functions

For the purposes of efficiency and readability, no single function should perform everything. Instead, think of one task that the function needs to complete and write it down to complete that task alone. Give the function a name that fits the task.

This makes it easier for others to read the code. The function will inherently be simpler and less extensive if you only work towards one task. Moreover, it allows you and your team to upload this function to another program if you need it later. Even with only the variable names and function titles passed, we get a clearer understanding of where to find certain tasks in the second version below.

function table (columns, rows, item)
creates table and searches it for the passed item

// compared to

function createTable (columns, rows)
//creates table

function searchTable (table.length, item) 
//searches table for the passed item

Use tools according to the problem

JavaScript is not a completely new programming language. It’s the same age as me. And in the most competitive field of computer science, a language that lasts so long must be something unique and powerful. When something already has a lot of power, web developers usually give it more by setting up directories. These are extremely powerful libraries that make many tasks easier. Although, in other cases, a library is designed for a specific purpose, like Facebook’s Reasonml. The reason is JavaScript flavor that 52% of developers do not know about! Now, as a developer, you have some specific requirements for the project you are working on. This special requirement can be submitted using a specific tool. For example, suppose you build a website for shipping Apple accessories, it is necessary for your website to provide a smooth UX on any device, especially on iPhone, iPad, macOS. But how do you make sure you do not have access to it all?

Cross-browser cloud-based testing tools like LambdaTest can help you test your site on more than 2000 browser combinations + operating system. So you can ensure smooth processing of sites on macOS, Windows, Android, iPhones, iPads and other devices.

5. Son DOM

When a page is loaded into a browser, the Document Object Model (DOM) is generated. This includes a number of levels that make it easier to access the various elements. With so many front-end frameworks and the widespread use of jQuery, you would think that knowing the DOM is no longer necessary. On the contrary, I believe that understanding how the DOM works is critical to becoming a JavaScript master. JavaScript has the ability to modify any HTML component. It can change the color of your background, your font anything. When JavaScript has so much power and is used so intensely within HTML, knowing what will affect what is required. As a programmer, you need to know how changing a child and parent property at the same time will affect the overall structure of the page. DOM is one of the basic and important things for a JavaScript developer and he needs to be an expert at it.

6. Treatment of memory leaks

In a JavaScript environment, memory leaks are a constant problem. When you save memory but do not need it or do not use it, it is known as a memory leak. Variables and objects are used to save memory. The result is a slowdown while running resulting in a slowdown of the site. It is not appreciated among the JS community. If you have an advantage in this among all developers, you will be preferred over all. There are many reasons that can cause memory leakage. These can vary from random global variables to set declarations (setInterval ()). It is necessary to remember these things. You can check for memory leaks by using the browser developer tool and then proceed to modify your code. See our article on eradicating memory leaks in JavaScript.

7. Understand the code of others

There will always be someone better than you when it comes to coding with JavaScript, no matter how good you are. There will always be a better reasoning for the same problem, no matter how good your logic is. If you’re serious about becoming a JavaScript master, accepting this reality should not be a problem.

Reading other developers’ code is a great way to expand your JavaScript skills. It’s better to see the code of each random problem, but it’s better to see the code of a problem you worked on. Work on the code whose solution fascinates you like a website. If you like a website and wonder how the developer got it, see the code. The problem has different solutions and it is better to know everything to learn how to reduce the complexity of JavaScript code. This, in turn, will make it easier for your site to load.

8. Read books

Reading from the book has few advantages of its own. First of all, every time someone writes a book about a language, he has a complete grasp and experience in this field. This is very important for beginners. The author can explain in an easy and understandable way quickly. On the other hand, this is not the case online. The internet is full of ambiguity. Many times you may come across two different conflicting points that are difficult to decide. It’s hard to trust a web page. When writing a book, it needs publishers and a good audience. An audience that is willing to spend their time, a lot of time actually, on a single book. It makes a great book and great books are by good writers.

9. Bookmark of reliable sources

In the point above, we discussed that the internet is easily accessible to anyone, hence anyone can put anything on the internet that he likes. There is no one to judge, check, etc. The other side of the internet is pretty cool. This side allows us to access everything in a second and very specifically. For example, if I want to learn array in JavaScript. I can just search for an array in JavaScript and I will only read about arrays in JavaScript. This is not the case with books where you have to find the arrays and read them for a minimum of 15-20 pages. Combining these two points, we come to the solution that the internet is good until you are viewing only a reliable source. Reliable sources can be anything like a reputable programmer / writer, giant companies like Microsoft or it can be acclaimed sites like w3schools. Always mark a reliable JavaScript source on the web. JavaScript is not a sentence that once said will remain forever. It’s growing. It changes all the time. Marking these pages will help you access everything in seconds. One such reliable source is Mozilla Developer Network.

10. Track developer communities such as Stack Overflow,Dev.to

Stack overflow is one of the most popular sites among computer science engineers. It was one of the main sources for understanding complex coding problems and concepts. It is not surprising that many companies monitor cartridge overflow for their problems as well. If you are not subscribed to Stack overflow, follow the JavaScript tag so you are always aware of issues that people face in JavaScript. Not only that, but you can also contribute by helping other people by providing solutions that you could not do on YouTube or any other site. It will help you refresh your skills. This will increase your points in Stack Overflow which makes you popular among the community and there is no doubt that a lot of great and good recruiters are looking for good coders in Stack Overflow. Landing in such a company will again help you hone your skills to become a JavaScript master.

11. Use Object Literals

When designing objects or arrays in JavaScript, you can save line space by selecting Shortcut. This is achieved by defining the properties or cells of an object or array during the statement and not afterwards.

This saves you the need to identify which object or array you define in each line, making the section easier to read. While this may seem like a small change, it can save a lot of eye strain for your team as objects and arrays become more complex.

Summary

So, while becoming a JavaScript developer is simple, becoming a JavaScript master is a little more challenging. It’s not simple enough to go over the concepts. It needs HTML that breathes life into HTML and allows you to see amazing elements that perform jobs you never dreamed of. The elements I mentioned earlier are essential in becoming a JavaScript expert. Remember them and apply them one by one. You are ready to compete with anyone and develop anything (imaginary or not) in the internet world after you have completed the goals outlined in each chapter. for life!
