How JS Works

How JavaScript Works

JavaScript is an interpreted language.

This means that the code is executed line by line.

Web browsers have a built-in JavaScript engine (like V8 in Chrome, SpiderMonkey in Firefox) that reads and executes the code.

Execution Context

When the JavaScript engine runs your code, it creates an execution context.

console.log("Step 1");
console.log("Step 2");
console.log("Step 3");
