In this article, we will learn how to get the same value from another array and assign it to an object of arrays. To get the same value from another array and insert it into an object of the array we need to.
- Compare each and every element of two arrays
- Return the matched element
- Add the element or object into the object of the array
We can do this by using the following methods:
Method 1: Using forEach() and push()
In this method, we will be using the forEach() and push(), includes() method of the array to get the same value from another array and assign it to the object of arrays.
Example:
Javascript
// Define first arraylet arr1 = [1, 2, 3, 4, 5, 77, 876, 453];// Define second arraylet arr2 = [1, 2, 45, 4, 231, 453];// Create a empty object of arraylet result = [];// Checked the matched element between two // array and add into result arrayarr1.forEach(val => arr2.includes(val) && result.push(val));// Print the result on consoleconsole.log(result); |
Output
[ 1, 2, 4, 453 ]
Method 2: Using filter() and push()
In this method, we will use the filter(), push(), and includes() of array to get the same value from another array and assign it to the object of arrays.
Example:
Javascript
// Define first arraylet arr1 = [1, 2, 3, 4, 5, 77, 876, 453];// Define second arraylet arr2 = [1, 2, 45, 4, 231, 453];// Checked the matched element between two array// and add into the result arraylet result = arr1.filter( val => arr2.includes(val));// Print the result on consoleconsole.log(result); |
Output
[ 1, 2, 4, 453 ]
