Using ES8 features with blockly build #172

Closed davidkmrcode closed 4 years ago

davidkmrcode commented 4 years ago

I tried to use async/await with the blockly build, but got the following when trying to make en:

[JSC_LANGUAGE_FEATURE] This language feature is only supported for ECMASCRIPT8 mode or better: async function.

Is there a way to use ECMASCRIPT8 features with the build?
