## Build Polyfills

This is a collection of syntax and import/export polyfills either copied directly from or heavily inspired by those used
by [Rollup](https://github.com/rollup/rollup) and [Sucrase](https://github.com/alangpierce/sucrase). When either tool
uses one of these polyfills during a build, it injects the function source code into each file needing the function,
which can lead to a great deal of duplication. For our builds, we have therefore implemented something similar to
[`tsc`'s `importHelpers` behavior](https://www.typescriptlang.org/tsconfig#importHelpers): Instead of leaving the
polyfills injected in multiple places, we instead replace each injected function with an `import` or `require`
statement.

Note that not all polyfills are currently used by the SDK, but all are included here for future compatitibility, should
they ever be needed. Also, since we're never going to be calling these directly from within another TS file, their types
are fairly generic. In some cases testing required more specific types, which can be found in the test files.
