JavaScript 101
A simple yet Indepth look into the marvellous language on web
What we need JavaScript ?
Early Web
All DATA MUST COME FROM SERVER !
Drawbacks
- Super Slow
- Super Costly
- Super Insane
Lets do some tricks on
the page itself
(Who knew that the language intended to interact
with webpages will end up controlling robots, yikes !)
MODERN WEB BROWSER
This is what turns ugly code to gorgeous usable interfaces
DOM & DOM TREE
Javascript was intended to handle this !
JavaScript
&
Java
Are light years apart
JavaScript
Lets try doing a hello world !
console.log("hello world");
Perhaps lets try out some numbers
var a = 0;
var b = 2;
console.log( a + b );
Syntax looks like C no ?
Variables & Data Types
Like Java everything here is an object,
but unlike java we are not POOP
more into the code
Iterators and Control Flows
Functions
Function Patterns
Classes & Objects
