How to use the ramda-extension.toUpperFirst function in ramda-extension

(deps: Dependencies, dep: string) => ({
    ...deps,
    [dep]: toUpperFirst(toCamelCase(dep))
  }),
  {}

const peerDependencies = Object.keys(pkg.peerDependencies);

const defaultGlobals: Dependencies = peerDependencies.reduce(
