Some different Syntaxes

const asHours = (duration) => {
 const stepOne = msToHours(duration);
 const stepTwo = valueIf(overOne(stepOne));
 const stepThree = falseOr(Math.round(stepTwo));
 const stepFour = falseOr(PostFixHours(stepThree));
 return stepFour;
}

// Or, if you're a mad man. Like this:
const asHours = (duration) => falseOr(postFixHours(falseOr(Math.round(valueIf(overOne(msToHours(duration)))))));
