Determines if a given value is a regular expression.

Usage Guide

Some usage examples for the isRegex function:

Basic Type Checking

import isRegex from './isRegex';

const pattern = /abc/;
console.log(isRegex(pattern)); // true

const nonPattern = 'abc';
console.log(isRegex(nonPattern)); // false

Validation before using regex methods

const maybePattern = '/[a-z]/';

if (isRegex(maybePattern)) {
    console.log(maybePattern.test('hello')); // Executes safely
} else {
    console.log('Not a valid regex pattern');
}

Filtering an Array

const items = [/test/, 'hello', /abc/, 123];
const regexItems = items.filter(isRegex);
console.log(regexItems); // [/test/, /abc/]
