JavaScriptで文字列が正規表現に合致するかどうかを判別する

Posted at

Solution: RegExp.prototype​.test()を使おう

  1. 正規表現を定義する
  2. チェックしたい文字列を定義した正規表現のtest()メソッドでチェックする
  3. Booleanで値が返ってくる
const validRegexFormat = RegExp('hoge*')
const string1 = 'hoge'
const string2 = 'bar'
console.log(validRegexFormat.test(string1)) // => true
console.log(validRegexFormat.test(string2)) // => false
