Debugging Tools in JavaScript

Debugging tools in JavaScript allow developers to identify and fix errors in their code. You can use features likeconsole.log(), the `debugger` command, and browser debugging tools.

Syntax:

Let's say we want to debug a function in JavaScript:

console.log("Debugging: ", variable);

function miFuncion() {
  const variable = "Hello World";
  debugger; // Activate the debugger at this point
  console.log(variable);
}

miFuncion();

Purpose:

Debugging tools allow you to inspect the code's state, pause it at specific points, and examine variables, making it easier to find errors and understand the execution flow.
