How would I sum for every number in each array each other

Well, this is a challenge in Hackerrank called Electonic Shop and this is my code, it works to a certain test. When the inputs increment the time of compilation gets more time. So I need to sum for every number in one array with the other numbers for the second array.

function getMoneySpent(keyboards, drives, b) {    let purchase = [];    let result = -1;      for(let i = 0; i < keyboards.length; i++) {     for(let j = 0; j < drives.length; j++) {       if((keyboards[i] + drives[j]) <= b) {        purchase.push(keyboards[i] + drives[j]);         result = Math.max(...purchase);        }       }     }     return result;  }    console.log(getMoneySpent([4], [5], 5)); // Should return  -1  console.log(getMoneySpent([3, 1], [5, 2 ,8], 10)); //Should return  9  console.log(getMoneySpent([40, 50, 60], [5, 8, 12], 60)) // Should return  58

I don't know how to make it more efficient.
