-String interpolation/variable substitution (i.e. injecting variables within text) is a really common operation when building single and multilingual applications. Existing string interpolation utilities within the most used `i18n` / `l10n` packages like `i18next` and `formatjs` come with massive overhead while lacking proper TypeScript infer support for the interpolation operation.
