What is wrong with the js code?

Question

JavaScript

/*Create a function that will take an array and a variable k ,

and return

true if the sum of any two members of the array is equal to k and false otherwise.*/

let n=0
let x=0

function func(arr,k){
    for(let i=0;
i<arr.length;i++)
{

if(n===arr[i]){
  x++

for(let i=0;
i<arr.length;i++)
{

  if(n+arr[i]===k){
      console.log(n)
      console.log(arr[i])
    return  true
  
   }}}}

  if(x<arr.length){                                 
n++
func(arr,k)        
 }
if(x>=arr.length){
return false
}
}
console.log(func([11,25,34,46,5],59))

Answer 1

Very interesting code, which will fall on the syntax check.

const hasPairSum = (nums, desiredValue) => {
    if(nums.length < 2) {
      return false;
    }
    const [firstNum, ...tailNums] = nums;
    const hasDesiredValue = tailNums.some((num) => firstNum + num === desiredValue);
    return hasDesiredValue || hasPairSum(tailNums, desiredValue);
  };
