When duplicates are removed, we can use the length property to get the number of unique elements. Hint: If you want to learn more about how to remove duplicates from an array in JavaScript, you should read How to Remove Duplicates From an Array in JavaScript! For example, suppose we have...
Array Basic Operations: Traverse, Insertion, Deletion, Search, Update. Other Array Methods Array Syntax An array can be diagnosed as such: Elements: Are items stored in the array. Index: Represents the location where an element is stored in an array. Length: Is the size of the array or th...
The ‘Array.unshift()’ is a built-in method in JavaScript frameworks likeSencha Ext JSwhich is used to insert one or more elements at the beginning of an array. The method not only modifies the original array permanently but also returns the new length of the array as well. Thereby, thi...
Retrieving Array Data Once data is stored in a two dimensional array, it is useful to have a means of reading the data again. As we are using a grid-like mapping between the board representation and the array storage representation, it would be nice to print the data in a grid-lik...
