Use jOrder. http://github.com/danstocker/jorder

Feed your array into a jOrder table, and add an index on the 'ID' field.

var table = jOrder(data)
    .index('id', ['ID']);

Then, get the array index of an element by:

var arrayidx = table.index('id').lookup([{ ID: MyID }]);

If you want the entire row, then:

var filtered = table.where([{ ID: MyID }]);

Voila.
