Javascript for loop

for loop is used to get the array value.

for(var i=0; i<5; i++){
	
console.log(i);

}

Suppose you have emp array

var emp=["John","Rom","Mathew","Sachin"];

Now, get the Array value

for(var i=0; i < emp.length; i++){
	
	console.log(emp[i]);

}

Note:- emp.length is used to count the number of array element.

var emp=["John","Rom","Mathew","Sachin"];
for(var i=emp.length-1; i >= 0; i--){
	
	console.log(emp[i]);

}

for(var i=0; i<=10; i=i+2)
{

	console.log(i);
}
