foreach vs for JS code example

Example 1: foreach in javascript

///Simple One
var a = ["a", "b", "c"];
a.forEach(function(entry) {
    console.log(entry);
});


///Function  concept

var fruits = ["apple", "orange", "cherry"];
fruits.forEach(myFunction);

function myFunction(item, index) {
  document.getElementById("demo").innerHTML += index + ":" + item + "<br>";
}

Example 2: for loop vs for each loop

1-
  For Loop:
-It is flexible to iterate array
both ascending and descending order.
  For Each:
-It iterates from initial to end

2-
  For Loop:
-It runs until given condition become false
  For Each: 
-Keeps execution until last element
get executed

3-
  For Loop:
-It use index
  For Each:
-It use iteration

4-
  For Loop:
-Accepts both object collections and non object collections
  For Each:
-Accepts only object collections

Example 3: for vs foreach loop
