JavaScript is a scripting language that is crucial in enabling interactive website features.
If it is turned off on an iPhone, web pages may not display correctly in Safari, leading to missing elements or broken functionality.
To ensure a seamless browsing experience, it is essential to keep JavaScript enabled.
Steps to Activate JavaScript on an iPhone
If you find that websites are not functioning as expected, follow these instructions to turn on JavaScript on your iPhone:

Once these steps are completed, JavaScript will be active, allowing websites to function correctly.
