If you want to use some es7 syntax, you could use babel-eslint by following this instruction. This should fix your issue.

The syntax you are using is experimental, so it's not built into ESLint/standard. Once it progresses to stage-4 of the standardization process then it will work out-of-the-box. You can set up babel-eslint using the instructions here: https://github.com/feross/standard#can-i-use-a-custom-js-parser-for-bleeding-edge-es-next-support
