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);
