Error: Unexpected token ...

It seems that Esprima is failing to parse code that uses the spread operator:

This started happening after I upgraded my project to use AJV 8.9.0. That version apparently uses the ellipsis/spread operator in the code it ships in its NPM package. Usages of the spread operator in my own code seem to be unaffected. Since then, I'm unable to build my project, because this parse error causes the webpack build to fail.

@BryceLohr I found same issue in esprima repo. I look like inactive it.
I will consider that migrate other parser.
