It's pretty obvious that composing by hand could easily be done in a similar fashion as we saw above with pipelining. For example, the unique word counting function that we wrote a couple of sections earlier, could be written in simple JS style:
const getUniqueWords1 = str => { const str1 = removeNonAlpha(str); const str2 = toUpperCase(str1); const arr1 = splitInWords(str2); const set1 = arrayToSet(arr1); const arr2 = setToList(set1); return arr2;};
Alternatively, it could be written more concisely (and more obscurely!) in one-liner style:
const getUniqueWords2 = str => setToList(arrayToSet(splitInWords(toUpperCase(removeNonAlpha(str)))));console.log(getUniqueWords2(GETTYSBURG_1_2));// [ 'A', 'AGO', 'ALL', ...
