CamelCase

 

WHAT I LEARNED
using regular expression
split() - The separator can also be a regular expression. 정규식을 split()의 separator로 사용가능.

 

let s = "camelCaseHowManyWords"

function CamelCase(str) {
    let re = /[A-Z]/g; //g is global
    //regular expression can separate a string at the instance there is a capitalized letter.
    let wordSplit = str.split(re); 
    let result = wordSplit.length;
    console.log(result); //5
}

CamelCase(s);
