What is ‘this’ in Javascript world?

In this short video tutorial I explain the basics of this keyword in Javascript. It’s a confusing concept for those starting out with Javascript.

-- QUICK INTRODUCTION TO this KEYWORD

-- If a function has a this reference in it, it points to an object. The object it points to depends on how the function was invoked.
-- It does not refer to the function itself.

function simpleFn() {
  console.log(this) // this points to an object
}

simpleFn() // -- window

let myObject = {
  myFunctionTwo: simpleFn,
  name: 'Ankur',
  age: 36
}

myObject.myFunctionTwo()

// strict KEYWORD
// .call(obj2)
