JS Logical Insanity

Question

This code returns min, how is this possible?

if(prices[i] == 1000 && min == 53){
  if(prices[i] < min){
    return min;
  }
  return prices[i];
}

Answer 1

The values are strings. When you use == to compare them to numbers, the numbers are first (internally) converted to strings. However, the < compares the two strings as strings, and as such the string "1000" is in fact less than the string "53", because "1" comes before "5" in the character set.

Answer 2

Funny things happen when you compare strings and not numbers

console.log("strings", "1000" < "53")
console.log("numbers", 1000 < 53)
