The JavaScript quantifier "m{X,}" is designed to operate on a series of text (m) that occurs a minimum of X times. The {X,} signifies a numerical value that indicates the minimum number of occurrences that should be matched within a string when utilizing the quantifier function in JavaScript. This regex quantifier functions within a string when employing methods such as regex search, match, test, and exec. Additionally, regex modifiers can be applied to the characters present in the string in conjunction with the quantifier.
Syntax
This syntax demonstrates the utilization of the regex "x" quantifier to obtain accessible characters.
/a{x,}/
/a{x,}/modifier;
Description
- The "a" is represented as an input character with the modifier.
- The "x" shows matching data at least given numbers such as 1,2, etc.
- The modifier uses global and case-insensitive with the regex quantifier.
Supported Browsers
The given browsers support the javascript regex {x,} quantifier.
- Google Chrome
- Internet Explorer
- Opera
- Safari
- Firefox
- Edge
Examples
The illustrations below demonstrate the application of the {x,} quantifier in JavaScript regular expressions. It is possible to utilize numerical values as characters within the quantifier.
Example 1:
Utilizing a quantifier regex, the provided instance correlates the "j" data with the sequence number's single and double digits. This allows for determining the presence of characters within the string.

function display_group() {
var sequance_pattern1 = "java, php, jquery, javascript, nodejs";
// Use regex {x,} quantifier for character input string
let input_pattern = /\j{1,}/g;
var quant_sequance1 = sequance_pattern1.match(input_pattern);
var ele = document.getElementById("regex_quant");
ele.innerHTML = "Available Values for one digit sequence: "+quant_sequance1;
// Use regex to get a minimum of two times the j character
let input_pattern1 = /\j{2,}/g;
var quant_sequance2 = sequance_pattern1.match(input_pattern1);
//get output of the available array character in the string
var ele1 = document.getElementById("regex_quant1");
ele1.innerHTML = "Available Values for two digit sequence: "+quant_sequance2;
}
</script>
</body>
</html>
Output
The quantifier in JavaScript provides multiple occurrences of availability values represented by "j".
Example 2:
The provided illustration correlates numerical digits with sequence numbers of two or three digits. This enables us to determine the characters available within the string.

function display_group() {
// Use regex {x,} quantifier with match method
var sequance_pattern1 = "2, 0, 200, 2000, 100";
let input_pattern = /\d{2,}/g;
var quant_sequance1 = sequance_pattern1.match(input_pattern);
var ele = document.getElementById("regex_quant");
ele.innerHTML = "Available Values for two digit sequence: "+quant_sequance1;
// Get a minimum of three times the digital numbers
let input_pattern1 = /\d{3,}/g;
var quant_sequance2 = sequance_pattern1.match(input_pattern1);
//get output of the available array character in the string
var ele1 = document.getElementById("regex_quant1");
ele1.innerHTML = "Available Values for three-digit sequence: "+quant_sequance2;
}
</script>
</body>
</html>
Output
In JavaScript, the quantifier can retrieve a total of "20" values within a string.
Example 3:
The provided sample examines the numerical values within a sequence, specifically focusing on two and five-digit numbers. This process yields a Boolean result indicating the presence of string characters within the sequence.

let input_pattern = /\d{2,}/g;
var quant_sequance1 = input_pattern.test(sequance_pattern1);

var ele1 = document.getElementById("regex_quant1");
ele1.innerHTML = "Available Values for five-digit sequence: "+quant_sequance2;
}
</script>
</body>
</html>
Output
The quantifier is employed to check for the presence of sequences of three or five numbers.
Example 4:
In this illustration, global and case-insensitive modifiers are applied alongside quantifiers of {x,}. By incorporating these modifiers, we can determine the distinction within a single character sequence.

Output
The quantifier is utilized to verify the existence of a singular sequence of numbers.
Conclusion
The {x,} quantifier is utilized to obtain a series of strings, characters, and numbers. It enables us to perform operations such as replacing, testing, matching, and filtering data using this quantifier.
