Unexpected token '??=' error

[mattyb]

Getting a syntax parsing error. I expect typescript-estree needs to be updated.

> react-scanner -c react-scanner.config.js

<redacted>/node_modules/react-scanner/node_modules/@typescript-eslint/typescript-estree/dist/convert.js:172
        result.range ??= (0, node_utils_1.getRange)(node, this.ast);
                     ^^^
