Let’s discuss and understand a concept which is very important in the present scenario. The test() method is a RegExp expression method.When I started teaching regular expression (regex or regexp), there were no sufficient resources! Being in this industry for almost 23 years now, and after exploring an ocean of digital content, I must say - Regex needs to be explained in a more simplified way. In JavaScript, the RegExp object is a regular expression object with Matches any string that contains zero or one occurrences of n Matches any string that contains zero or more occurrences of n Matches any string that contains at least one n Quantifiers define quantities: Quantifier Metacharacters are characters with a special meaning: Metacharacterįind a match at the beginning of a word like this: \bWORD, or at the end of a wordįind the Unicode character specified by the hexadecimal number xxxx Perform a global match (find all matches rather than stopping after the first match)īrackets are used to find a range of characters: Expressionįind any of the characters between the bracketsįind any of the digits between the bracketsįind any of the alternatives separated with | Modifiers can be used to perform case-insensitive more global searches: Modifier Regular expressions can make your search much more powerful (case insensitive for example). Regular expression arguments (instead of string arguments) can be used in the methods above.
