Use Mitt as the Event Emitter (#5907)
* chore: migrate to Mitt as the EventEmitter

This commit moves us to using Mitt [1] for the event emitter in
Puppeteer. This removes our dependency to Node's EventEmitter which is
part of a larger stream of work to enable a Puppeteer-web version that
doesn't depend on Node.

There are no large breaking changes as we support the main methods that
EventEmitter had, but it also provides some methods that Puppeteer
didn't use. Technically end users could depend on this but it's
unlikely.

DocLint

Doclint is a small program that lints Puppeteer's documentation against Puppeteer's source code.

Doclint works in a few steps:

  1. Read sources in lib/ folder, parse AST trees and extract public API
    • note that we run DocLint on the outputted JavaScript in lib/ rather than the source code in src/. We will do this until we have migrated src/ to be exclusively TypeScript and then we can update DocLint to support TypeScript.
  2. Read sources in docs/ folder, render markdown to HTML, use puppeteer to traverse the HTML and extract described API
  3. Compare one API to another

Doclint is also responsible for general markdown checks, most notably for the table of contents relevancy.

Running

npm run doc

Tests

Doclint has its own set of jasmine tests, located at utils/doclint/test folder.

To execute tests, run:

npm run test-doclint
