Let's use objectValues function already implemented in @optimizely/js-sdk-utils package (

javascript-sdk/packages/utils/src/index.ts

Line 61 in 19bc495

export function objectValues<K>(obj: { [key: string]: K }): K[] {

).

@mjc1283 I removed values from fns altogether. there was only one usage, i used objectValues from js-sdk-utils directly there
