Create a Variable: const

The const keyword is used to declare variables that have a constant value, meaning their value cannot be reassigned once it is set. This is particularly useful when you have a value that should remain constant throughout your code.

Syntax

To declare a constant variable, it's similar to the var and let syntax, just use the const keyword followed by the variable name and the initial value assigned to it. Here's the syntax:

1const pi = 3.1415;
2const message = "Hello, World!";
3
4console.log(pi); // Output: 3.1415
5console.log(message); // Output: Hello, World!
