Array methods - Basic JavaScript Fast (31) | splice, concat, forEach, indexOf, filter, map, join

We discuss a number of methods that can be used in arrays for JavaScript. The splice method helps us to delete and insert elements at a certain index. The slice method helps to extract a portion of an array. The concat method joins two arrays and allows appending of new elements. The forEach method allows us to apply a user-defined function for each of the elements in an array. The indexOf method returns the index of a given element in an array. The filter method retrieves the objects that satisfy some given conditions from an array of objects. The map method accepts an array, calculates some quantities, and returns an array of answers. The split method separates a string into distinct words. The join method combines separate strings in an array into a single string.
