Explain the MUL() function in JavaScript ?

0 0 1 minute read

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`s 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:

30
24
