I do not have the possibility of checking it, but if I remember correctly

"1.200" == "1.2"
Enter fullscreen mode Exit fullscreen mode

is true because since both sides "look" like floating point numbers, they are converted both to float before doing the comparison.

console.log('1.200' == '1.2'); // false
console.log(1.2 == '1.2'); // true
console.log('1.200' == 1.2); // true

MDN: Equality (==) — Comparison with type conversion

  • If the operands are of different types, try to convert them to the same type before comparing:
    • When comparing a number to a string, try to convert the string to a numeric value.
    • If one of the operands is a boolean, convert the boolean operand to 1 if it is true and +0 if it is false.
    • If one of the operands is an object and the other is a number or a string, try to convert the object to a primitive using the object's valueOf() and toString() methods.
