Proposal: rename `page.evaluate` into `page.eval`

Justification:

• page.evaluate is actually doing eval in a page
• page.evaluate is probably the most used method, it’s tiring to type the whole word every time

@paulirish @ebidel wdyt?

On the ‘cons’ side:

• every other library has evaluate: nighmare.js, phantom.js, chromeless, chrominator, chromy,…
• it’s easy to have a shortcut if needed:

let page = await browser.newPage();
page.eval = page.evaluate;

I’m not convinced we need it, I’d rather not make it to minimize entropy.

I’m disappointed in you @ebidel. :shipit: exists.
