Anders Kaseorg 6ec808b8df js: Add "use strict" directive to CommonJS files.
ES and TypeScript modules are strict by default and don’t need this
directive.  ESLint will remind us to add it to new CommonJS files and
remove it from ES and TypeScript modules.

// HAPPY PATH: most translations are a simple string:
if (context === undefined) {

/*
context will be an ordinary JS object like this:
{minutes: minutes.toString()}
This supports use cases like the following:
i18n.t("__minutes__ min to edit", {minutes: minutes.toString()})
We have to munge in the context here.
