* Lint arrow-body-style * Lint prefer-object-spread Object spread is faster _and_ more readable. This also fixes a few unnecessary object clones. * Enable no-parameter-properties This isn't currently used, but this makes clear that it shouldn't be. * Refactor more Promises to async/await * Remove unnecessary code from getDataMoveHTML etc * Lint prefer-string-starts-ends-with * Stop using no-undef According to the typescript-eslint FAQ, this is redundant with TypeScript, and they're not wrong. This will save us from needing to specify globals in two different places which will be nice.
