// Note: Currently, we use the REST API for Operand because of some unpkg/webpack issues.
// In the future, we'd like to use the SDK (https://github.com/operandinc/typescript-sdk).
// If someone knows how to do this w/o breaking the Operand typescript-sdk for npm users,
// please let Morgan (@morgallant) and/or (@_jzhao) know! <3
