About regexp.prototype.flags
In the ever-evolving world of JavaScript, developers continuously seek tools that streamline their coding practices while adhering to the latest standards. The npm package "regexp.prototype.flags" serves precisely this need by providing an ES6 spec-compliant shim for RegExp.prototype.flags. This package ensures that developers can utilize the full capabilities of regular expressions in JavaScript, particularly the ability to access the flags used to perform the regex match. This compatibility with the ECMAScript 2016 (ES6) standard enhances code maintainability and future-proofs projects by aligning with current specifications.
To integrate this functionality into your project, the process is straightforward: simply use the command `npm install regexp.prototype.flags`. This command installs the package into your node modules, allowing you to leverage the enhanced regex capabilities immediately in your JavaScript environment. The inclusion of this package ensures that your application handles regular expressions as defined in the ES6 specification, providing a robust foundation for pattern matching and string parsing tasks that are critical in many development projects.
The key benefit of using "regexp.prototype.flags" in your development stack is its seamless integration and compliance with ES6 standards, ensuring that your regex operations are both powerful and predictable. Developers can confidently use flags within regular expressions to specify global searches, case-insensitive searches, and more, without worrying about compatibility issues across different JavaScript engines. This npm package not only simplifies the development process but also enhances performance and reliability in handling complex regex operations, making it an indispensable tool for modern web development.

RegExp.prototype.flags 
An ES6 spec-compliant RegExp.prototype.flags shim. Invoke its "shim" method to shim RegExp.prototype.flags if it is unavailable.
Note: RegExp#flags requires a true ES5 environment - specifically, one with ES5 getters.
This package implements the es-shim API interface. It works in an ES5-supported environment and complies with the spec.
Most common usage:
var flags = require('regexp.prototype.flags');
assert(flags(/a/) === '');
assert(flags(new RegExp('a') === '');
assert(flags(/a/mig) === 'gim');
assert(flags(new RegExp('a', 'mig')) === 'gim');
if (!RegExp.prototype.flags) {
flags.shim();
}
assert(flags(/a/) === /a/.flags);
assert(flags(new RegExp('a') === new RegExp('a').flags);
assert(flags(/a/mig) === /a/mig.flags);
assert(flags(new RegExp('a', 'mig')) === new RegExp('a', 'mig').flags);
