What is const in Javascript

`const` is a JavaScript keyword used to declare a variable whose value cannot be reassigned after initialization.

It stands for "constant," meaning the value set cannot be changed later in the code.

const pi = 3.14;
console.log(pi); // Outputs: 3.14

This line would cause an error because a constant variable cannot be reassigned.

Attempting to do so results in a TypeError: Assignment to constant variable.
