How to reverse an array in javascript. for this task you can use the reverse() method to reverse the order of the elements in the array. as you may guess, this method reverses an array in such way that the first array element becomes the last array element and the last array element becomes the first. here’s an example for you:. There are two ways to create an array in javascript. the simplest way to create an array is using the array literal notation: alternatively, you could use the global array class constructor to initialize a new array: to create an empty array, use the empty brackets: spaces and line breaks are permitted. Here is an example of an array with four elements: type number, boolean, string, and object. const mixedtypedarray = [100, true, 'freecodecamp', {}]; the position of an element in the array is known as its index. in javascript, the array index starts with 0, and it increases by one with each element.

Every element in the array is assigned with an index. by default, the first index of an array is zero. to retrieve a specified element from an array, a pair of square brackets enclosing the index value is used, i.e., cars [0]. to avoid any confusion, think of the index as the number of items to skip, counting from the start of the array. With arrays, there are usually a set number of specific things you want to achieve. below is a list of pretty much any action you would want to perform on an array, and how to do it in javascript. if you have any more, let me know in the comments below! 1. find the index of an element by value. use indexof:.
