Developer Tools secrets that shouldn’t be secrets

1. Console is much more than `log()`!

What is that you’re logging?


Adding to your console vocabulary

Errors and assertions in Console

Tracing where something came from

Grouping console messages

Displaying and filtering lots of information in the console as tables

$$('a').map(a => {
return {url: a.href, text: a.innerText}

2. You can log without source access — live expressions and logpoints

3. You can log outside the browser — VS Code debugger

4. You can inject code into any site — snippets and overrides.

5. You can inspect and debug much more than you know!
