Const is a keyword used in programming languages to declare that a variable's value cannot be modified once it is assigned. It's like a promise that you make to the compiler (and to other developers) that you won't try to change the value later on, which can help prevent bugs and make your code more predictable.

How to use it in a sentence

• "I'm going to declare this variable as const because I know it's never going to change, just like Facebook's privacy policy."

• "Using const is a good way to communicate your intentions to other developers, assuming they actually read your code instead of just copying and pasting from Stack Overflow."
