Example of Arrow Function in JavaScript

The following code shows an Example of Arrow Function in JavaScript.

Basically, we use arrow functions when we need to write a concise function. It represents a shorter syntax of the function. The following code example shows an arrow function to find the power of a number.

<html>
  <head>
    <title>Arrow Functions in JavaScript</title>
    <script>
      let powerFunction = (x, y) => {
          p=1;
          for(i=1;i<=y;i++)
	  {
		p=p*x;
	  }
	  return p;
       };
      function findPower()
      {
	a=Number(prompt('Enter the value of x: '));
	b=Number(prompt('Enter the value of y: '));	
        alert(a+' raise to the power '+b+' is '+powerFunction(a, b));
      }
     </script>
    <style>
       div{
         margin: 100px;
         padding: 50px;
         border: 2px black solid;
         text-align: center;
        }
    </style>
  </head>
  <body>
	<div>
		<button onclick="findPower()">Find Power</button>
        </div>
