JavaScript is a powerful scripting language that enhances the functionality of websites by enabling dynamic and interactive elements.
Many websites rely on JavaScript for features such as animations, form validation, and interactive menus.
If JavaScript is disabled on your iPhone, certain web pages may not function properly or may appear broken when viewed in the Safari browser.
If you are experiencing issues with website functionality, you may need to enable JavaScript on your device.
Below is a detailed guide on how to turn on JavaScript in Safari on an iPhone.
