// without HOC
const greaterThan5Words = word => word.length > 5;
// We may also want to have a dynamic length.  To do that we can create an HOC:
const createLengthTest = minLength => word => word.length > minLength
// Now we can re-write our greaterThan5Words
const greaterThan5WordsNew = createLengthTest(5)
// The added advantage of this is that now we can create more variants:
const greaterThan3Words = createLengthTest(6)
const greaterThan20Words = createLengthTest(20) // etc.
