How JavaScript Engine Works?

To understand the JavaScript engines you have to understand what goes into it when we compile and execute our code. Once you completely read the article, you’ll be able to write an excellent piece of code. The article is about JavaScript engines, which will help you to understand the performance of JavaScript engines and its most valuable features.

What Are JavaScript Engines?

JavaScript engines are a program that helps in converting your code of JavaScript into a lower level code or machine code. ECMAScript Standards is being followed by the JavaScript engines. The job of these standards is to give a definition, how JavaScript engines should work. It also tells what all features it should have.

If we talk generally, high-level languages such as JavaScript, C, FORTRAN have been abstracted from machine language. In comparison to C or C++, JavaScript is abstracted much farther from the machine level. C and C++ are much closer to hardware among other reasons that make it much faster.

Compilation and Interpretation

Compilation and interpretation are few approaches that are used generally for the implementation of the code by programming languages.

A compiler can be defined as a program that helps in transforming a code. This transformation is done for the code that has been written in any programming language (source language) into another programming language that was targeted by you. They perform this task by translating the source code from a much high-level programming language to a low-level programming language i.e. machine language.

An interpreter analyses your source code line by line and instruction by instruction and then performs the execution of the corresponding machine code on the targeted machine directly without any involvement of a third party.

Although compilation and interpretation are the two principles with the help of which the implementation of the programming languages is done, they are also related to each other in some cases. This relation comes out as most of the systems that use interpretation do perform some works of translation. The translation work is done by compilers also.

If we talk about the category of JavaScript then it belongs to the interpreted category, even after it has been compiled technically. Today’s modern compilers of JavaScript performs the Just-In-Time (JIT) compilation that occurs at the time of running.

JavaScript engines are made connected to browsers and web servers, e.g. Node JS, so that you should have permission for run-time compilation and execution of JavaScript code.

The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /
<script type="text/javascript">
