Writing code that works is good; writing code that is readable and reliable is better. A handful of habits make all the difference.

Habits worth adopting

• Choose clear names for your variables and functions (total rather than x).
• Reach for const by default and let only when you need it.
• Comment the tricky parts so you can pick the code up again easily.
• Split your code into short functions, each with one clear job.
• Test regularly in the console and fix errors as you go.

Keep making progress

JavaScript is a vast language. Once you have these foundations, you can explore arrow functions, frameworks such as React, or more advanced asynchronous programming. The most important thing: practise regularly on small, concrete projects.

Well done: you now have solid JavaScript foundations. Clear, tested, well-structured code: you are ready to build your own projects!
