How do I activate Javascript and what does it mean?

On many websites the message appears that you have to activate Javascript. We'll tell you what Javascript is all about and how to turn it on in your browser.

What is Javascript?

• Javascript is a programming language. It is used to execute complex program sequences in a website. This function should already be activated in your browser by default.
• A standard website consists of an HTML core. If websites are expanded with Javascript, dynamic content can be used on them, for example animations. Javascript also allows websites to adapt to their users.
• Only certain parts can be reloaded on websites. Online shops in particular can no longer do without this technology. For this reason alone, you should activate Javascript. But also so that other web content is displayed correctly and works as it should.
