- [ ] Provide a **test plan** demonstrating that the code is solid.
- [ ] Match the **code formatting** of the rest of the codebase.

## Motivation (required)

What existing problem does the pull request solve?

no "use strict" in es modules

## Test Plan (required)

A good test plan has the exact commands you ran and their output, provides screenshots or videos if the pull request changes UI or updates the website. See [What is a Test Plan?][1] to learn more.

If you have added code that should be tested, add tests.
