Js in bits - &#use strict&#)

Learning js should be fun. It's fun if it's easy.
I tried my best in writing this, to understand it easily.

'use strict'

Js is backwards compatible
The old code never breaks as they are not removed after all these years.

Problem: Because of this any bugs introduced at the start are still present today.

Solution: 'use strict'
It will result in error for old bugs.

Using 'use strict' at the start of .js file or start of function makes the rest of the code safe.

Leave y'r thoughts....
