Question

I have no idea how to solve this Question I want to use RECURSION for this(我不知道如何解决这个问题，我想为此使用RECURSION)

I would appreciate it if you answer for me ...

(如果您为我回答，我将不胜感激。)

Question(题)

• Write a function called "modulo".

  (编写一个称为“模”的函数。)

• Given 2 numbers, "modulo" returns the remainder after dividing num1 by num2

  (给定2个数字，“取模”将num1除以num2后返回余数)

• Notes:

  (笔记：)

• Do NOT use the actual built-in modulo (aka "remainder") operator (%) in your implementation.

  (Do NOT使用实际的内置模（也称为“余数”） operator (%) 。)

• Modulo always returns the sign of the first number.

  (模数总是返回第一个数字的符号。)

output(输出)

let output = modulo(25, 4);
console.log(output); // --> 1

My code(我的密码)

function modulo(num1, num2) {


  // termination
  if (num1 - num2 === 0 ) {
    return 0;
  }
  // base
  if (num1 - num2 === 1 ) {
    return 1;
  } 
  // RECURSION

  return modulo(num1,num2)  

}
