Check if an array contains any element of another array in JavaScript

Question

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:

Answer 1

My solution applies Array.prototype.some() and Array.prototype.includes() array helpers which do their job pretty efficient as well

ES6

const originalFruits = ["apple","banana","orange"];

const fruits1 = ["apple","banana","pineapple"];

const fruits2 = ["grape", "pineapple"];

const commonFruits = (myFruitsArr, otherFruitsArr) => {
  return myFruitsArr.some(fruit => otherFruitsArr.includes(fruit))
}
console.log(commonFruits(originalFruits, fruits1)) //returns true;
console.log(commonFruits(originalFruits, fruits2)) //returns false;
