CoffeeScript String - match()

---

Description

This method is used to retrieve the matches when matching a string against a regular expression. It works similar to regexp.exec(string) without the g flag and it returns an array with all matches with the g flag.

Syntax

Given below is the syntax of match() method of JavaScript. We can use the same method in the CoffeeScript code.

string.match( param )

Example

The following example demonstrates the usage of match() method of JavaScript in CoffeeScript code. Save this code in a file with name string_localecompare.coffee

str = "For more information, see Chapter 3.4.5.1";
re = /(chapter \d+(\.\d)*)/i;
found = str.match re
         
console.log found 

Open the command prompt and compile the .coffee file as shown below.

c:\> coffee -c coffee string_match.coffee

On compiling, it gives you the following JavaScript.

// Generated by CoffeeScript 1.10.0
(function() {
  var found, re, str;

  str = "For more information, see Chapter 3.4.5.1";

  re = /(chapter \d+(\.\d)*)/i;

  found = str.match(re);

  console.log(found);

}).call(this);

Now, open the command prompt again and run the CoffeeScript file as shown below.

c:\> coffee string_match.coffee 

On executing, the CoffeeScript file produces the following output.

[ 'Chapter 3.4.5.1',
  'Chapter 3.4.5.1',
  '.1',
  index: 26,
  input: 'For more information, see Chapter 3.4.5.1' ]
