dent

dent

The closest you can get to DEstructuring assignmeNT with good old ES5's objects and functions.

Example

dent for arrays:

> var tuple = ['first', 'second', 'third']

> dent(tuple)
> var a = dent() // Or in a single statement: dent(tuple)()
> var b = dent()
> var c = dent()

> dent.idx
3 // Next element's index.

> [a, b, c]
[ 'first', 'second', 'third' ]

dent for objects:

> var pair = { first: 'foo', second: 'bar' }

> dent(pair)
> var a = dent.o.first // Or in a single statement: dent(pair).o.first
> var b = dent.o.second

> [a, b]
[ 'foo', 'bar' ]

API

dent(obj)

Save reference to obj in dent.o. Return the dent itself.

dent.o

Object passed to dent the last time.

dent()

Return the next element (with index dent.idx) and increment dent.idx by 1.

dent.idx

Next element's index (as would be accessed by dent()).

Warning

dent storage is temporary. Drop your object in, take it apart, but don't assume that it will sit in dent.o or dent.idx will be the same next time you check.

Install

npm install dent
