    // Regarding "no-var": The opinion of this repository's maintainers is that
    // while const/let are useful, the use of `var` is not bad and therefore
    // does not need to be ruled out. Eliminating the use of `var` would be a
    // large diff that (a) could theoretically cause bugs due to lexical scoping
    // changes and (b) could theoretically impact perf (e.g. see
    // https://github.com/microsoft/TypeScript/issues/52924). New code MAY
    // prefer const/let over `var`. Code in "examples/" MUST use const/let --
    // this is enforced by "examples/.eslintrc.json".
