Why the plus operator not working well

Question

https://code.sololearn.com/W55yk126GEft/?ref=app

Answer 1

use parseInt(or parseFloat), like these :
res = parseInt(a) + parseInt(b) or
input=parseInt (prompt(...))

Answer 2

const input1 = Number(prompt("Enter first num: "));
const operator = prompt("Enter an operator");
const input2 = Number(prompt("Enter second num: "));

Answer 3

It working like concatination because prompt accept string type basically..
Convert into into number type value by
const input1 = Number(prompt("Enter first num: "));

Or
const input2 = +prompt("Enter first num: ");

Both value..
For, other it will automatically converted but for plus, it works both ways : addition and concatination overloaded operator...
Hope it helps...
