JavaScript String match() Method
JavaScript String match() method is an inbuilt function in JavaScript used to search a string for a match against any regular expression. If the match is found, then this will return the match as an array.
Syntax:
string.match(regExp);
Parameters:
- regExp: (i.e. regular expression) which will compare with the given string.
Return Value:
It will return an array that contains the matches and one item for each match or if the match is not found then it will return Null.
Example 1: In the example, the substring “eek” will match with the given string, and when a match is found, it will return an array of string objects. Here “g” flag indicates that the regular expression should be tested against all possible matches in a string.
javascript
// Initializing function to demonstrate match()// method with "g" parafunction matchString() { let string = "Welcome to geeks for geeks"; let result = string.match(/eek/g); console.log("Output : " + result);} matchString(); |
Output : eek,eek
Example 2: In this example, the substring “eek” will match with the given string, and it will return instantly if it found the match. Here “i” parameter helps to find the case-insensitive match in the given string.
javascript
// Initializing function to demonstrate match()// method with "i" parafunction matchString() { let string = "Welcome to GEEKS for geeks!"; let result = string.match(/eek/i); console.log("Output : " + result);} matchString(); |
Output : EEK
Example 3: In this example, the substring “eek” will match with the given string, and it will return instantly if it found the match. Here “gi” parameter helps to find the case-insensitive match AND all possible combinations in the given string.
javascript
// Initializing function to demonstrate match()// method with "gi" parafunction matchString() { let string = "Welcome to GEEKS for geeks!"; let result = string.match(/eek/gi); console.log("Output : " + result);} matchString(); |
Output : EEK,eek
