I am trying to trying to wrap all three functions in one.
const sentence_read = (str) => [alphabet_count(str), word_count(str), vowel_count(str)]
will return an array with your 3 results. Usage :
let str = "a word";
console.log(sentence_read(str)) // output : [6, 2, 2]
Using a template string
let str = "i am writing an algorithm.";
// function to count alphabets
const alphabet_count = (str) => str.length;
// function to count words
const word_count = (str) => str.split(" ").length;
//function to count vowel
const vowel_count = (str) => (str.match(/[aeiou]/gi)).length;
const sentence_read = (str) => `a_c : ${alphabet_count(str)}, w_c : ${word_count(str)}, v_c : ${vowel_count(str)}`
console.log(sentence_read(str)) // a_c : 26, w_c : 5, v_c : 8If you want to group the functions in an object, you can use:
const str = "i am writing an algorithm.";
const counter = {
alphabet: (s) => s.length,
word: (s) => s.split(" ").length,
vowel: (s) => (s.match(/[aeiou]/gi)).length
}
const count = (unit, str) => {
if(!counter[unit]) throw Error('Unit does not exist')
return counter[unit](str)
}
console.log(count('alphabet', str)) // 26
console.log(count('word', str)) // 5
console.log(count('vowel', str)) // 8
