JavaScript: Tips of the Day
var functionName = function() {} vs function functionName() {}
The difference is that functionOne is a function expression and so only defined when that line is reached, whereas functionTwo is a function declaration and is defined as soon as its surrounding function or script is executed (due to hoisting).
For example, a function expression:
// TypeError: functionOne is not a function functionOne(); var functionOne = function() { console.log("Hello!"); };
Historically, function declarations defined within blocks were handled inconsistently between browsers. Strict mode (introduced in ES5) resolved this by scoping function declarations to their enclosing block.
'use strict'; { // note this block! function functionThree() { console.log("Hello!"); } } functionThree(); // ReferenceError
