javascript - push multiple elements to array -

i'm trying force multiple elements 1 array, getting error

> = [] [] > a.push.apply(null, [1,2]) typeerror: array.prototype.push called on null or undefined

i'm trying similar stuff i'd in ruby, thinking apply *.

>> = [] => [] >> a.push(*[1,2]) => [1, 2]

when using functions of objects apply or call, context parameter must object working on.

in case, need a.push.apply(a, [1,2]) (or more correctly array.prototype.push.apply(a, [1,2]))
