example.ts

/**
 * Check URL against Regular Expression
 *
 * @param string url
 * @return string|boolean
 */
function parseYoutubeId(url: string): string|boolean {
    const regexp: RegExp = new RegExp('(?:youtube(?:-nocookie)?\.com/(?:[^/]+/.+/|(?:v|e(?:mbed)?)/|.*[?&]v=)|youtu\.be/)([^"&?/\s]{11})', 'i');
    const matches: string[] = url.match(regexp);
    
    return matches ? matches[1] : false;
}

/**
 * Test a URL against our regular expression
 *
 * @param string url
 * @return void
 */
function test(url: string): void {
    const result: string = parseYoutubeId(url);
    
    console.log(result);
}
