const toString = (x: number) => x.toString();
 
const result = pipe(5, add, double, toString);
console.log(result); // ((5 + 1) * 2).toString() => "12"
 
 
const split = (str: string) => str.split(' ');
const getLength = (arr: string[]) => arr.length;
const isEven = (num: number) => num % 2 === 0;
 
const hasEvenWordCount = pipe('hello world from typescript', split, getLength, isEven);
console.log(hasEvenWordCount); // true (4 words)
