This prevents the use of Async Iteration - through for await (... of ...)
statements:
for await (const line of readLines(path)) {
console.log(line)
}
These will not be allowed because they are not supported in the following browsers:
- Edge < 79
- Safari < 12
- Firefox < 57
- Chrome < 63
This can be safely disabled if you intend to compile code with the @babel/plugin-proposal-async-generator-functions
Babel plugin
