JAVASCRIPT: Difference between UNDEFINED and NULL

Javascript Undefined vs NULL

Many a times we often get confused on whats the difference between UNDEFINED and NULL.
undefined means a variable has been declared but has not yet been assigned a value. On the other hand, null is an assignment value. It can be assigned to a variable as a representation of no value.
Also, undefined and null are two distinct types: undefined is a type itself (undefined) while null is an object.
Unassigned variables are initialized by JavaScript with a default value of undefined. JavaScript never sets a value to null. That must be done programmatically.


Is PINTEREST spamming?

{EAV:89877567cae0a34d}Lately, Pinterest have really grown enormously. It has very intuitive design and very good concept of visual bookmarking. Infographics shared on pinterest are just amazing, you get to know all the collated information at one page, in one single very attractive image.

Today, while pinning I came across a page, saying, scavenger hunt price. It was clearly a pinterest page but when you click on any of the listed gift, it takes you to another site. That, another site, was surely a SPAM as detected by anti-virus. Guys beware of such spams
