You can use Array.prototype.filter like this
var result = array.filter(function(currentObject) {
return currentObject.b === 2;
});
console.log(result);
# [ { a: 1, b: 2 } ]
You can also do this with plain for loop, like this
var result = [];
for (var i = 0; i < array.length; i += 1) {
if (array[i].b === 2) {
result.push(array[i]);
}
}
console.log(result);
# [ { a: 1, b: 2 } ]

how can I use that 'return'?

filter will gather all the items for which the function returns true and all those items will be available in result, like I have shown in my example.var result;
for (var i = 0; i < array.length; i += 1) {
if (array[i].b === 2) {
result = array[i];
break;
}
}
console.log(result);
use a break to make some difference.
