![]() ![]() Elements that return true are added to the new array created by the filter(). Check out this full stack development course to learn more about Javascript. The callback method is triggered when the filter method iterates over the elements of the array. It has a single parameter, known as the callback method. Instead of mutating the array on which it was called, filter() creates a new array. Let us start with final bit of this article on Removing Elements From An Array In JavaScript, Array Filter Method The code removes all occurrences of the element “Blues”. ![]() JavaScript allows us to remove multiple elements from the array. The code removes the element “Blues”, after finding out the index position of the element. Find the index position of "Blues," and remove one element from that position In the following example, we remove the element “Blues”: If the element is not found, it returns -1 as the output. This method can be paired with the indexOf() command, which returns the first index at which a given element can be found. We can search for an element using splice(), and remove it consecutively. Remove Elements By Value: Removing Elements From An Array In JavaScript, The code removes the values mentioned in the splice method. Starting at index position 0, remove two elements It is plausible to remove consecutive elements by using the splice() method: Moving further with, this article on Removing Elements From An Array In JavaScript, Splice For Range Of Elements It must be noted that arrays are zero-indexed in JavaScript. “Blues” and “Jazz” are removed, as the index specifies that 2 elements must be removed, starting at index 2. “Blues” is removed from the first example as it is placed at index 2. In the above example, the slice method removes the elements according to the index specified. Starting at index position 2, remove two elements Starting at index position 2, remove one element It proves to be resourceful method of removing, replacing or adding elements to the array. The splice() method removes a particular or a selective part of the array. Join our UX Design Courseand become a design superstar. On using the unshift() method, “Rock” will be added back to the array. The unshift() method, on the other hand, adds the element back to the beginning of the array. ![]() The shift() method removes the element from the beginning of an array. Shift Method: Removing Elements From An Array In JavaScript The push() method appends the element back to the array. ![]() The code removes the last element in the array i.e. The methods implement the concept of LIFO (Last-In-First-Out). The push() method, on the other hand, adds an element to the end of an array. The pop() method removes the element from the end of an array, much like a stack. Let us get started then, Removing elements from an array in JavaScript Following are the pointers this article will focus on, In this article, I will be walking you through various methods for removing elements from an array in JavaScript. There are various methods for such manipulations, one of which includes the method for removing an element. Most often then not there is a need for manipulating an array which arises from nowhere. ![]()
