File contents

Avoid JavaScript-based redirects

JavaScript redirects force an additional round-trip after the initial page load, significantly increasing the time users spend waiting for content.

Quick Reference

Use 301 or 302 server-side redirects instead of window.location
JS redirects delay page load as the browser must first download and execute the script
Client-side redirects can negatively impact SEO and indexability

Check

Check the project for instances where JavaScript is being used for page-level redirects (e.g., window.location).

Fix

Replace JavaScript-based redirects with server-side 301 or 302 redirects in your web server or edge configuration.

Explain

Explain why server-side redirects are faster and more SEO-friendly than client-side JavaScript redirects.

Code Review
