The **`string.match()`** is a built-in function in JavaScript; it is used to search a string, for a match, against a [regular expression](https://www.educative.io/shoteditor/4879445779283968/preview). If it returns an Array object the match is found, if no match is found a Null value is returned.

# Syntax
The syntax for `string.match()` is shown below:

## Regular expression

It has two things
* an expression that needs to be searched or replaced

* a modifier that modifies the search

|   modifiers  |  meaning   |
| --- | --- |
|  **g**    | It searches the expression at *all instances*.    |
|  **i**   |  It performs *case-insensitive* matching.  |

## Examples

1.  This example shows a regular expression with a 'g' modifier

var data = 'Welcome to the Educative! Everyone likes Educative';
// regular expression with 'g' modifier
var regExp = /Educative/g;
// string.match() function.
var found = data.match(regExp);

// printing an array object.
console.log(found);

2.  This example shows a regular expression with a 'i' modifier

var data = 'Welcome to the Educative! Everyone likes Educative';
// regular expression with 'i' modifier
var regExp = /educative/i;
// string.match() function.
var found = data.match(regExp);

// printing an array object.
console.log(found);

3. This example shows a regular expression with both a 'g' and an 'i' modifier

var data = 'Welcome to the Educative! Everyone likes Educative';
// regular expression with 'g' 'i' both modifier
var regExp = /educative/gi;
// string.match() function.
var found = data.match(regExp);

// printing an array object.
console.log(found);
