cherrypick

cherrypick props off an object

What

Check out the example

Example

Grab it:

var cherrypick = require('cherrypick');

Use it:

var someObject = {
    a:1,
    b:2,
    c:3
};

var picked = cherrypick(someObject, 'a b');

picked will be:

{
    a:1,
    b:2
}

You can switch to exclude mode by passing true as the second parameter:

var someObject = {
    a:1,
    b:2,
    c:3
};

var picked = cherrypick(someObject, true, 'a b');

picked will be:

{
    c:3
}

You can also pick on dot-notated deeply nested keys:

var someObject = {
    a:1,
    b:2,
    c:3,
    d:{
      e:{
            g:4
        },
        f:{
            h:2
        }
    }
};

var picked = cherrypick(someObject, 'a d.e.g');

And you can change the name of keys using a tuple syntax:

var someObject = {
    hello: 'world',
    things:{
        stuff: 'majigger'
    }
};

var picked = cherrypick(someObject, 'greetings:hello things.whatsits:stuff');

->

{
    greetings: 'world',
    things:{
        whatsits: 'majigger'
    }
}
