TL;DR

Narrow down bug scope 🎯

First, identify cases for which the issue occurs.

Then, you can analyze corresponding defective code.

Navigating whole code base for fixing a bug is:

Localize the bug before fixing it.

Spend some time learning about:

You don’t need to learn all of them.

Only the ones that are useful for your stack.

Find what works. Use them often.

Every bug is a failing test case.

Use tests to:

Remember:
Test >> Bug documentation

They prevent future appearance of the bug.

It’s a fancy term for “Thinking out loud”.

Idea is to explain your code line by line to a rubber duck.

It forces you to come out of the perspective that introduced bugs in the first place.

Also, the tip works with pets too :)

While debugging you will get stuck.

A lot!

So limit the time spent in a session.

After that, take a break.

Let your mind wander.

Clear your head and come back later.

This tip works best for me.

That’s it.
