So, i hope you have learned something new and keep on practicing as there is no other way around in programming. Use each function to add class : each jQuery JavaScript Tutorial 1. var number = // Traditional Way number.forEach(function(element, index) ,100) console.log(sum) // es6 way var sum = number.reduce((total, value) => total + value ,100) console.log(sum) /* Expected Output 143 */ The callback is called for each element in the array, in order, skipping non-existent elements in sparse arrays.
When called it iterates over the DOM elements that are part of. forEach accepts a callback function and, optionally, a value to use as this when calling that callback (not used above). When you perform certain action using ForEach loop it changes the data on the original array. forEach will iterate over the array you provide and for each iteration it will have element which holds the value of that iteration. each() method is designed to make DOM looping constructs concise and less error-prone. Foreach method is most common way to loop through the array.įoreach takes a callback function and executes the function once for each array element.īasically, it loop through every element of array one by one, and perform some actions on them.
