): boolean {
  return this.hasOpening(opening) && this.hasClosing(closing);
}

Basic

// Example usage.
import { Wrap } from '@angular-package/wrapper';

// Returns true. Checks `[]`.
new Wrap(`[`, `]`, 'quote').isWrapped();

// Returns false.

new Wrap(``, `]`, 'quote').isWrapped();

// Returns false.
// It's not wrapped cause of closing chars are an empty string.
new Wrap(`[`, ``, 'quote').isWrapped();

// Returns false.
new Wrap(``, ``, 'quote').isWrapped();

Given opening

// Example usage.
import { Wrap } from '@angular-package/wrapper';

// Returns true. Checks `[]`.
new Wrap(`[`, `]`, 'quote').isWrapped('[');

// Returns false.
new Wrap(`[`, `]`, 'quote').isWrapped('[', '');

// Returns false. Checks `<]`.
new Wrap(`[`, `]`, 'quote').isWrapped('<');

// Returns false.
// It's not wrapped cause of opening chars are an empty string.
new Wrap(``, `]`, 'quote').isWrapped('<');

// Returns false.
// It's not wrapped cause of closing chars are an empty string.
new Wrap(`[`, ``, 'quote').isWrapped('[');

// Returns false.
// It's not wrapped cause of closing chars are an empty string.
new Wrap(`[`, ``, 'quote').isWrapped('[', ''),

Given closing

// Example usage.
import { Wrap } from '@angular-package/wrapper';

// Returns true. Checks `[]`.
new Wrap(`[`, `]`, 'quote').isWrapped(undefined, ']');

// Returns false. Checks `[>`.
new Wrap(`[`, `]`, 'quote').isWrapped(undefined, '>');

// Returns false.
// It's not wrapped cause of opening chars are an empty string.
new Wrap(``, `]`, 'quote').isWrapped(undefined, ']');

// Returns false.
// It's not wrapped cause of opening chars are an empty string.
new Wrap(``, `]`, 'quote').isWrapped(``, ']');

Given opening and closing chars

// Example usage.
import { Wrap } from '@angular-package/wrapper';

// Returns false.
new Wrap(`[`, `]`, 'quote').isWrapped('[', ']');

// Returns false.
new Wrap(`[`, `]`, 'quote').isWrapped('[', '>');

// Returns false.
new Wrap(`[`, `]`, 'quote').isWrapped('<', ']');

// Returns false.
new Wrap(`[`, `]`, 'quote').isWrapped('<', '>');

// Returns false.
