Using FindWhere With Nested Objects In An Array
I have a data structure that looks like this
var foo = [
{
bar: {
something: 123
},
baz: {
somethingElse: 321
}
},
{
bar: {
something: 444
},
baz: {
somethingElse: 555
}
}
];
I then have a variable:
var findMe = 444;
I'd like to search through my foo
data structure (an array of objects) to see if findMe
matches the bar.something
property of any of the objects inside the foo
array.
Using underscore.js, I would have thought the following code snippet would do the trick:
var _ = require('underscore');
var thingImLookingFor = _.findWhere(foo, {bar.something: findMe});
However that produces a syntax error in my application:
Uncaught SyntaxError: Unexpected token .
Is anyone able to shed some light on how I can achieve the search I'm looking for?
Thanks!

Answer
Found out the solution to my question.
_.find() does what I want quite nicely.
_.find(foo, function(obj) {
return obj.bar.something == findMe;
});
