mixy

Sugar methods to manipulate objects.

Methods

var mixy = require('mixy')
// actually `mix === mixy`
var mix = mixy.mix

r = mix(r, ...sources)

Mix own properties from all sources into the receiver object r.

var o = { x: 1 }
mix(o, { x: 2 }, null, { y: 3 }, { x: 4 })
// o == { x: 4, y: 3 }

r = fill(r, defaults)

Mix own properties from defaults into the receiver object r, except those r already owns.

var o = { x: 1, y: 2, z: null, w: undefined }
fill(o, { x: 2, z: 3, w: 4, a: null, b: undefined })
// o == { x: 1, y: 2, z: null, w: undefined, a: null, b: undefined }

o = pick(keys, ...sources)

Pick properties specified in keys from sources to create the returned object.

var o = pick(['x', 'y'], { x: 1, y: 2 }, null, { x: 3 })
// o == { x: 3, y: 2 }

o = pick('x', { x: 1, y: 2 }, { x: 3 })
// o == { x: 3 }

o = exclude(keys, ...sources)

Pick properties except thos specified in keys from sources to create the returned object.

var o = exclude('y', { x: 1, y: 2 }, null, { x: 3 })
// o == { x: 3 }

o = exclude(['x', 'y'], { x: 1, y: 2, z: 3 }, { x: 3, z: 4 })
// o == { z: 4 }

o = del(keys, target)

Delete keys from target, and return a new object containing those deleted key-values. If none is deleted, null will be returned.

var o = del('y', { x: 1, y: 2 })
// o == { y: 2 }

var o = del('z', { x: 1, y: 2 })
// o == null

o = del(['x', 'y'], { x: 1, y: 2, z: 3 })
// o == { x: 1, y: 2 }
