Edit Question
Title
Body
NOTE : This question was asked from the viewpoint of ECMAScript version 3 or 5. The answers might become outdated with the introduction of new features in the release of ECMAScript 6. What exactly is the function of the var keyword in JavaScript, and what is the difference between var someNumber = 2; var someFunction = function() { doSomething; } var someObject = { } var someObject.someProperty = 5; and someNumber = 2; someFunction = function() { doSomething; } someObject = { } someObject.someProperty = 5; ? When would you use either one, and why/what does it do?
