A Closure is a feature in JavaScript where a function "remembers" the variable from its lexical Scope(the scope in which it was created) even after the outer function has finished executing. This allows inner functions to access variables from their enclosing scope, even if the outer function is no longer active.

Example of Closure

function outerFunction(outerVariable){
  return function innerFunction(innerVariable){
     console.log(`outer variable : ${outerVariable}`);
     console.log(`inner variable : ${innerVariable}`);

};}

const closureFunction = outerFunction('outside');
closureFunction('inside');
