Must i learn JavaScript before i learn API.? And what's the difference between java and java script ?

You can learn Python to create API's too. Java and JavaScript are two completely different languages and they serve a different purpose as well. Java is really good for mobile apps (Android) and it is a cross-platform language overall. JavaScript rules the Web, but you can code mobile apps with it too by using frameworks like React Native. If you are a beginner try JavaScript :)

Java is to Javascript as car is to carpet

There is no more or less important. Everything depends on the goal that you want to achieve. Both languages have advantages and disadvantages.

Java is to JavaScript as Car is to Carpet means they are in no way directly connected. Can you compare a car with carpet? It's like so. Yes, they both have the word "Java" in their names, however, each language has its own syntax, plugins, frameworks, etc.

U mean more important right?

Thanks

Thank you so much

I asked the same question. You can continue with the JS tutorial Happy Coding!
