Can't get version 8.1.0 to run in IE11

This might be as simple as a one word answer: “no”, but I can’t find anywhere explicitly stating it.

The version of Ajv you are using 8.0.1 The environment you have the problem with Internet Explorer 11 Your code (please make it as small as possible to reproduce the issue)

const options = {
  code: { es5: true },
};
const ajv = new Ajv(options);
ajv.compile(schema);
ajv.validate(formData);

It breaks on the class declaration.

I have tried transpiling it with babel:

module: {
  rules: [
    {
      test: /node\_modules\/.*(ajv)\/.*\.js$/
      use: {
        loader: 'babel-loader',
        options: { presets: '@babel/preset-env' }
      }
    }
  ]
}

As well as adding targets: { ie: '11' }. There are various subsequent errors, but eventually I got stuck on it not accepting the pattern key in a JSON schema: with or without a RexExp around the compileSchema function.

That was exactly the issue! IE11 works fine with:

const options = {
  unicodeRegExp: false,
  code: { es5: true },
};
const ajv = new Ajv(options);

// webpack.config.js
module: {
  rules: [
    {
      test: /node\_modules\/.*(ajv)\/.*\.js$/
      use: {
        loader: 'babel-loader',
        options: { presets: '@babel/preset-env' }
      }
    }
  ]
}

Thank you!
