javascript - Argument type Number is not assignable to parameter type String|Function

Question

var str = name.toUpperCase();
var ch = new Array();
ch = str.split('');

for(var i=0;i<7;i++)
{
  if(ch = null) {
    result_code.replace(
      pos.toString()+pos.toString()+pos.toString()+pos.toString(),
      "FFFF");
  } else {
    var temp = parseInt(ch[i]);
    var temp_integer = 64;
    if(temp<=122 & temp>=97) {
      var pos = i+1;
      result_code.replace(
        pos.toString()+pos.toString()+pos.toString()+pos.toString(),
        (temp - temp_integer)+40);
    }
  }
}

This code is creating the error at this line result_code.replace(pos.toString()+pos.toString()+pos.toString()+pos.toString(), (temp - temp_integer)+40);.

The underlined information is this section (temp - temp_integer)+40.

The error shown is Argument type Number is not assignable to parameter type String|Function.

What is wrong with this code? I am using WebStorm. I am likely just making a dumb mistake. Thanks in advance!

The replace method accepts a string or a function as second parameter. Turn your value into a string: ((temp - temp_integer)+40).toString().
