JavaScript will NOT convert strings to numbers when adding:
let x = "100";
let y = "10";
let z = x + y;
document.getElementById("demo").innerHTML = z;
JavaScript will try to convert strings to numbers in all numeric operations like * (multiply), / (divide) and − (minus). JavaScript uses the + operator to concatenate the strings.
