JavaScript: Convert a given string into an array of words

JavaScript fundamental (ES6 Syntax): Exercise-103 with Solution

Write a JavaScript program to convert a given string into an array of words.

• Use String.prototype.split() with a supplied pattern (defaults to non-alpha as a regexp) to convert to an array of strings.
• Use Array.prototype.filter() to remove any empty strings.
• Omit the second argument, pattern, to use the default regexp.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 
const words = (str, pattern = /[^a-zA-Z-]+/) => str.split(pattern).filter(Boolean);
console.log(words('I love javaScript!!')); 
console.log(words('python, java, php'));

Sample Output:

["I","love","javaScript"]
["python","java","php"]
