Our code for today will give us example on how to Create, Read, Update and Delete (CRUD) items in a JavaScript array. This technique will give you full control over the fields and values of each array item. Example use of this code is when you have long rows of input elements and wanted to detect only the elements with inputted values, get their id, value and other related information. You won't have to loop through all the input elements to check if there are inputted values. This is because, you can instantly add an item to the array if the value was inputted, edit it when the value were changed, delete it when the value were removed and then read it for posting or later use. We can achieve better performance. Here is a video demo:
