//two sum : 
//Input: nums = [2,7,11,15], target = 9
//Output: [0,1]
//Explanation: Because nums[0] + nums[1] == 9, we return [0, 1].

var twoSum = function (nums, target) {
  for (let index in nums) {
    const remaining = target - nums[index]
    const output = nums
    output.splice(index, 1,null)
    if (output.includes(remaining)) {

      return [nums.indexOf(remaining), index]
    }

  }
}



var twoSum = function(nums, target) {
	let obj = {}
    for(let i = 0; i < nums.length; i++) {
        if (obj.hasOwnProperty(target-nums[i])) {
            return [obj[target-nums[i]], i]
        }
        obj[nums[i]] = i
    }
};
