Best Practices To Adjust With The Changing Syntax of JavaScript


How To Adopt The Change?

If you have been working with the JavaScript for pretty long time, then you might have faced plenty of changes in your journey. Because JavaScript is rapidly changing and developing. One day you are simply working on JavaScript and next morning you see a new series of JavaScript features.

To be honest, it’s a good thing that JavaScript developers are constantly working to improve it, but sometimes it’s too much. It’s too much that in the end, it started to affect the work as developers have to waste their time on understanding new features of JavaScript after few days.

Well, if you want to adopt the change, then goes back to the basics. Like, if you want to understand the Rails, then start polishing your Ruby skills. Similarly, if you want to use flow data in React with the webpack, then start sharpening your core JavaScript.

So, in short, to adopt the change quicker, start with the basic principles of programming languages. Because today languages change their features like weather, but if you have knowledge of the basic concept of the language. Then, no change can affect you in any way.

But, in the case of JavaScript, one tiny obstacle is still present as some new JavaScript features totally boycott the principles of old JavaScript. But, hey, not all the principles are challenged so you don’t have to worry much. So, people taking changing syntax of JavaScript in mind we would like to offer some solution to you.

Go With The Old

Well, if you are using new JavaScript and trying to introduce old JavaScript feature to it. Then, you might see the problem in debugging code or silently failing of the code. And, this is very common because in numerous cases, older codes won’t work on the new versions.

So, in such case, we recommend you to perform a function on the older version of the JavaScript. It will help you in getting the desired result as you always get in your reliable older version.

let and const Behaves Differently Than var

In the traditional JavaScript, var is used to declare the variable, but in the modern JavaScript, var is replaced with the let and const. And, which may we tell you would work totally different than each other. Like, declaring at the beginning of code considered as clean practice. But, let has few features which distinguish it from the var.

Variable declarations with var were always hoisted to the top of their containing scope by default, regardless of where they were placed inside of that scope. That meant that even a deeply nested variable could be considered declared and available right from the beginning of its containing scope. The same is not true of let or const.

Splitting Function

Traditionally function is used to define the function keyword, the extension area of the function can be varied. It can be also used with the new keyword to constrict the objective with the prototypal inheritance. Functions defined in both types can be called before and after the declaration.

And, this is usually lots of keywords for the one developer, that’s why more than one developer is required to do the job. That’s why in the new JavaScript, the function is divided into two parts arrow functions and classes.

New Arrow Function

Another difference that you will observe in the traditional JavaScript and new JavaScript is that the arrow function can be now easily accessed. A new syntax allows you to write callable action more neatly and it fits more perfectly. Moreover, the new syntax is so simple that it can be narrated in the one line.

Wrap Up

So, as you see people, it is the demand of the time to develop new features in the JavaScript. But, it doesn’t mean that your old methods are now not applicable. It’s just your choice whether you want to stick with old methods or are you ready to adopt the change.

That’s why guys, change is good. It’s just the matter of adjusting and adopting it. And, readers, whether in the world of JavaScript or the real world, always welcome change positively.
