function composition - 05

Function composition : 

Function composition is a mechanism by which we can combine multiple functions into a single complicated higher-order function. Here the result will come or move from right to left.

const upperCase = (replaceWord) => {
 return replaceWord.map(
   (revWord) => `${revWord[0].toUpperCase()}${revWord.substr(1)}`
 );
};

const joinText = (arr) => {
 return arr.join(" ");
};

const result = (text) => {
 return joinText(upperCase(replaceWord(words(text))));
};

const text =
 "My name is mozahedul islam. and I wanna be a great programmer in the world.";
 
console.log(result(text));
