Programming is hard. Well, anything technical is inherently hard. With that out of the way, today I’m writy a short post to let you in on a secret about what is pragma in the world of programming languages.
Pragma is short for pragmatic information. So, simple. In plain English, pragmatic is an adjective that means sensible and practical. In programming, pragma refers to:
pragma does not contribute anything to the programming language itselfpragma only affect the compiler behaviorpragma‘s syntax may vary🤔 JavaScript also has few pragmas, one of them is strict.
'use strict';By the above pragma, the JavaScript code will be executed in strict mode. In strict mode, bad syntax isn’t allowed, hoisting isn’t
done, silent errors are shown, etc. It helps in writing a more secure and optimized JavaScript code.
That’s about it.
