JavaScript: Redirect to a specified URL

JavaScript: Exercise-157 with Solution

Redirect to URL

Write a JavaScript program to redirect to a specified URL.

• Use Window.location.href or Window.location.replace() to redirect to url.
• Pass a second argument to simulate a link click (true - default) or an HTTP redirect (false).

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
// Define a function 'redirect' that redirects the browser to a specified URL
// If 'asLink' is true, it uses the current window's location to navigate to the URL
// If 'asLink' is false, it replaces the current window's location with the specified URL
const redirect = (url, asLink = true) =>
  // Check if 'asLink' is true
  asLink
    // If true, assign the specified URL to the current window's location href, causing navigation to the URL
    ? (window.location.href = url)
    // If false, replace the current window's location with the specified URL
    : window.location.replace(url);

// Call the 'redirect' function with a URL to redirect the browser to
redirect('https://google.com'); // Redirects the browser to 'https://google.com'
