jQuery - $.each loop through json code

Define a stack
Define an array
LOOP on each character in the string
    IF the top item of the stack is a single or double quote THEN
        LOOP through each character until you find a matching single or double quote, then pop it from the stack.
    ELSE
        IF "{", push onto the stack
        IF "}" THEN
            pop a "{" from the stack if it is on top
            IF the stack is empty THEN //we just finished a full json object
                Throw this json object into an array for later consumption
            END IF
        END IF
        IF single-quote, push onto the stack
        IF double-quote, push onto the stack
    END IF
END LOOP
