Two Sums

Given an array of integers nums and an integer target, return indices of the two numbers such that they add up to target.

var twoSum = function(nums, target) {
    for (let i = 0; i < nums.length; i++) {
        const num = nums[i];
        const rest = nums.slice(i+1);
        for(let m = 0; m < rest.length; m++) {
            const subNum = rest[m];
            if(subNum + num === target) {
