Given below is the syntax mentioned: RegExpObject.test(string) Pattern.test(text) – Will be the RegEx method test ().pattern.exec(text) – Will be the RegExp method exec().arch(pattern) – Will be the string method search().text.match(pattern) – Will be the string method match().If this method finds an equal then it will give back a ‘true’ otherwise it will give back a ‘false’, which in JavaScript the regular expression of searching for the test can be carried out with various methods and search with the pattern as a regular expression The RegEx test() method in JavaScript has been utilized to examine a string for getting an equal string. In Ex.3, ‘ive2’ is not existing in the given string of ‘Informative’ so the test will give back the ‘false’.In Ex.2, MAP is existing but we have not appended the ‘i’ modifier for case sensitiveness hence it will give back a ‘false’.In Ex.1, the ‘map’ is existing in the string of ‘Informative’, hence it will give back a ‘true’.We conclude that the ‘/map/i’ is a regular expression, ‘map’ is a pattern that can be utilized in the search, and ‘i’ is the modifier that authorizes the search to be case sensitive. the test then it will give back the Boolean value in the output.
In the above three examples, we have used the test method to find out if there are equal. The regular expression has been described to carry out significant pattern matching and it can search and replace functions on next.Įx.1: console.log ("Equal String: ",/map/i.test('Informative')):Įx.2: console.log ("Case Sensitive: ",/MAP/.test(' Informative')):Įx.3: console.log ("Non-equal String: ",/ive2/.test(' Informative')) The regex.test() method has been utilized to equate the string in which the method can give back true or false. The string is the parameter that is required that we need to pass as a string for searching for an equal string, and the return type of it is a Boolean in the form of true or false. If it is found equal then it will give the ‘true’, if it is not found equal then it will give back the ‘false’. The test() method of JavaScript carries out a search to find the equal between the regular expression and the defined string. The test() method has been used whenever we desire to know whether a pattern is established in the string.It can perform a search operation to find an equivalent between the regular expression and the given string which can give output in true or false.The RegEx is standing for the Regular Expression which is very significant in finding the text string, especially while filtering the text files. And it can be utilized to look for the equivalent string in the middle of the actual string and the regular expression which can give back result in the form of true if it finds an equal or false if it does not finds an equal. JavaScript RegEx test method is a method that gives back an array having all equal groups in which it can receive a string that we have to test as opposed to the regular expression.
