History of Array.prototype.every()

Standardise "Return value" section

clr review; thx!

Added a "Return value" section to the "Syntax" box, so that it’s quicker and easier to see what the function returns, in line with the "Parameters" section. Other function pages already have this and this is an effort to standardise that across the board.

add ES draft

cleanup

callback's first argument is required and the others are not.

Revert to revision of 2015-01-12 14:02:08 by SphinxKnight: "The ES6 spec uses "Array.prototype.every ( callbackfn [ , thisArg] )" so it is "callbackfn" instead of "predicate" there. Rolling this back to callback."

callback->predicate

Adding polyfill tag
