How Compilation Works
Explore how JavaScript runs through compilation by JavaScript engines like the V8 engine in Chrome. Understand the process from source code parsing to bytecode creation and machine code execution using JIT compilation, which accelerates runtime performance by translating code efficiently. This lesson helps you grasp how modern JavaScript engines optimize execution versus older interpretation methods.
We'll cover the following...
Introduction
Let’s understand precisely how JavaScript works. We need to see how the language is engineered in order to use it effectively.
What makes JavaScript run?
Generally, JavaScript is compiled and/or executed by JavaScript Engines. These JavaScript Engines are computer programs that execute JavaScript codes. These engines use one of the following techniques to run JavaScript: ...
