Explain the MUL() function in JavaScript ?

  • Last Updated : 25 Jul, 2021

The MUL function is a miniature of the multiplication function. In this function, we call the function that required an argument as a first number, and that function calls another function that required another argument and this step goes on. 

The first function’s argument is x, the second function argument is y and the third is z, so the return value will be xyz.

Syntax:

function mul(x) {
  return function (y) {
    return function (z) {
      return x * y * z;
    };
  };
}

Example: Below example illustrates the MUL() function in JavaScript.

Javascript




<script>
function mul(x) {
  return function(y) {
    return function(z) {
      return x*y*z;
    };
  }
}
  
console.log(mul(2)(3)(5));
console.log(mul(2)(3)(4));
</script>

Output:
