You can also apply css styling to certain messages in the console, if you need something to stand out. Use console.log("%cTEXT", "color: purple; font-size: 20px")

I've made a small npm package to better handle "tagged and colored" console.logs: npmjs.com/package/@pelv/frontlog

Nothing special but it has some fancy feature (hide log on prod build).
This post make me realise i should add the table and dir consoles, even if they doesn't really need styling.

Yes! that's also a great way of identifying the log messages at different run points in your code for easy debugging.

Thank you!🚀

Please stop using the console.* Methods for debugging... There is a reason why breakpoints and the debugger was invented ..

Another alternative is to just write perfect code in the first place. Much easier that way.

Did you ever try to debug a vue/react/... appliation, it simply does not work in most cases to place a breakpoint or get to a specific line, due to the compiling and optimizing. So console.log is the last resort.

Yes, but you are right, it takes some setup to get the debugger working on a Vue or react app... But it's possible.

Thanks for this article. There is one thing I wish you would have added.
console.log({}). This way of debugging helps when we need to name the output's that we are printing on the console.

e.g: console.log({testData: 'abc'});

We can directly use variables in the console.log in the above way that will give us the name of the variable along with the output.

The importance of gaming in Javascript is vast. It helps with hand-eye coordination, problem solving, and logic skills. Gaming can also relieve stress, improve moods, and promote social interaction.

This is really great!
Another trick I've been using so far to debug multiple variables is to print them all in a object. i.e:
console.log({ var1, var2, var3 });
