myFunc();What is Closures in JavaScript
/*A closure is the combination of a function bundled together (enclosed) with references
to its surrounding state (the lexical environment). In other words, a closure gives you
access to an outer function’s scope from an inner function. In JavaScript, closures are
created every time a function is created, at function creation time.*/
function init() {
var name = 'Mozilla'; // name is a local variable created by init
function displayName() { // displayName() is the inner function, a closure
alert(name); // use variable declared in the parent function
}
displayName();
}
