find-map

Combination of Array.find and Array.map.

Find an element but return any truthy result.

Why

This is handy for nested finds, where you want to retrieve the leaf node, eg.

Usage

``js
var findMap = require('find-map');

var items = [
{
subItems: [
{
targetItem: false,
value: 123,
foo: 0
}
]
},
{
subItems: [
{
targetItem: false,
value: 456,
foo: 0
},
{
targetItem: true,
value: 789,
foo: 0
}
]
}
]

var subItem = findMap(items, item => item.find(subItem => subItem.targetItem));
`

Limitations

Because find relies on a truthy response, you can't return a falsey value from find-map.

You can get around this fairly trivially by wrapping the value for return:

`js

var fooResult = findMap(items, item =>
item.find(subItem =>
subItem.targetItem && [subItem.foo] // Wrap the possibly falsey value in an array.
)
);
var result = fooResult && fooResult[0] // unwrap the value.
