Time to unmask the man behind this work!
@Shanshrew has created a novel parser architecture which is 2x - 3x faster.
Pleased to announce that we’re collaborating to integrate it into Oxc.
The speed-up is real, and massive! https://t.co/Wha59D3j0w
overlookmotel (@overlook_motel): This weekend I was shown something astonishing. Oxc’s parser is already the fastest JS/TS parser available. Now someone has found a way to make it even faster - by up to 3x! A tour-de-force of engineering, based on a truly novel approach. 🤯 Watch this space…
