why we use foreach loop in javascript code example

Example 1: javascript foreach example

var colors = ["red", "blue", "green"];
colors.forEach(function(color) {
    console.log(color);
});

Example 2: foreach in javascript

const avengers = ['IronMan','thor', 'captain america', 'hulk'];
avengers.forEach((item, index)=>{
	console.log(index, item)
})

Example 3: javascript foreach syntax

const marks = [12, 17, 14];
let sum = 0;

marks.forEach(mark => {
  sum += mark;
});
