Clearing array with setting length to 0 replaced with [] for being short and marginally efficient. For reference: [] is turned into a sequence of around 15 machine instructions on x64 (if bump pointer allocation succeeds), whereas a.length=0 is a C++ runtime function call, which requires 10-100x as many instructions.
