A closure is a feature in JavaScript where an inner function has access to the outer (enclosing) function’s variables!

Here is an example of a very uncommon closure in javascript:

const name = 'Mohammad Ali';  function innerFunction(){    
console.log(name);
}
innerFunction();

The function innerFunction() has access to the variable name. The outer scope of the file in which the code resides, while there is no explicit function declaration - the function innerFunction() having access to a variable name satisfies the condition of a inner function having access to an outer scope variable.

function outerBodyFunction() {
const name = 'Mohammad Ali';
function innerFunction(){
console.log(name);
}
return innerFunction;
}
let _innerFunction = outerBodyFunction();
// or outerBodyFunction()();
_innerFunction();
