7 kyu Vowel Count

題目說明:

函式帶入字串判斷有幾個母音(a,e,i,o,u)

code
export class Kata {
  static getCount(str: string): number {
    //code
    const lowerCaseStr = str.trim().toLowerCase();
    const regex = /[aeiou]/g;
    const matches = lowerCaseStr.match(regex);

    if (matches) {
      return matches.length;
    } else {
      return 0;
    }
  }
}

#TypeScript #string.match() #RegEx
