JavaScript is quickly evolving to meet the changing needs of the digital environments and new frameworks. Developers should understand well how to take advantage of the changes that can help them improve their skill sets, save the time and also make the difference between writing good codes and great codes.
Understanding the features of modern JavaScript can help you decide when to use the latest syntax to your best advantage and when it makes sense to use the traditional techniques. JavaScript best practices can be found on the net, but following the latest features can make things perform better.
Here in this blog, I will share with you some of the most important practices that can help you do better.

Determine The Version Suitable For You:
It is always good to know more about the version of JavaScript your browser is using and the exact environment that you are running the scripts on. Use the latest JavaScript version that is supported by your browser.
Avoid Using Javascript Keywords As Variables:
Like other languages, JavaScript also owns a set of keywords or some reserved words and since each of these has a specific purpose, they can’t be used as variable, function or method names or labels. Details of each are easily available on the net.
Few words like abstract, float, final, transient, short are not recommended to use because all these variable names are not compliant with all browsers.
Use Inline Commenting:
Most scripting or programming languages allow adding inline comments and so does JavaScript. It helps to reduce the complexity of codes by using meaningful text that is easily understandable by the developers. During JavaScript development, developers should maintain commenting and they should keep it short, a single line while using the inline style.
Use Strict Mode Strictly:
If you are working in the environment that is not conducive to modern JavaScript, then this practice is for you. The “use strict” mode helps in a variety of ways.
This directive imposes some law and order in JavaScript programming by enforcing such things that are declared as variables and does not allow using preserved keywords and prevents the use of “with” statements.
So, you should make the habit of using the “use strict” directive as it will help you to write better codes that are more test friendly and easier for the programmers to understand.
