lodash: mapping array to object

Question

Is there a built-in lodash function to take this:

var params = [
    { name: \'foo\', input: \'bar\' },
    { name: \'baz\', input: \'zle\' }
];

Answer 1

You should be using _.keyBy to easily convert an array to an object.

Docs here

Example usage below:

var params = [
    { name: 'foo', input: 'bar' },
    { name: 'baz', input: 'zle' }
];
console.log(_.keyBy(params, 'name'));

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.4/lodash.min.js"></script>

If required, you can manipulate the array before using _.keyBy or the object after using _.keyBy to get the exact desired result.

Answer 2

Yep it is here, using _.reduce

var params = [
    { name: 'foo', input: 'bar' },
    { name: 'baz', input: 'zle' }
];

_.reduce(params , function(obj,param) {
 obj[param.name] = param.input
 return obj;
}, {});
