Check if an array contains any element of another array in JavaScript
arrays, javascript
Solution
Vanilla JS
ES2016:
const found = arr1.some(r=> arr2.includes(r))
How it works
`some(..)` checks each element of the array against a test function and returns true if any element of the array passes the test function, otherwise, it returns false. `includes(..)` both return true if the given argument is present in the array.
Problem
I have a target array `["apple","banana","orange"]`, and I want to check if other arrays contain any one of the target array elements. For example: ``` ["apple","grape"] //returns true; ["apple","banana","pineapple"] //returns true; ["grape", "pineapple"] //returns false; ``` How can I do it in JavaScript?
