Beyond console.log

intro

As much as I hope that things will always work from first try, better to be prepared to debug it. console.log remains the main tool to do it, because it is the simplest and fastest.

Few console methods are known to everybody, log, warn and error.

Going deeper

There are more tricks to it.

count

For example, if you need to count how many times component re-render can use console.count, e.g. console.count('comp1')

After click

dir

Can log properties of an object with console.dir

time

Can measure how long some operation takes with console.time

Clear things up with console.clear()
