Console log this JavaScript
Simple example code.
<!DOCTYPE html>
<html>
<body>
<script>
console.log(this);
</script>
</body>
</html>Output:
The following four rules apply this in order to know which object is referred to by this keyword.
- Global Scope
- Object’s Method
- call() or apply() method
- bind() method
If a function that includes the ‘this’ keyword, is called from the global scope then this will point to the window object.
<script>
var myVar = 100;
function WhoIsThis() {
var myVar = 200;
console.log("myVar = " + myVar);
console.log("this.myVar = " + this.myVar);
}
WhoIsThis();
</script>Output: myVar = 200
this.myVar = 100
