 * What is the hell?
 *  - This is a automated script to do n numbers of facebook comments.
 *
 * Perpose of the hell?
 *  You may seen such kind of post
 *    - If you do  2K or 10K comments, your facebook friend will do xyz... (may be he/she will be naked🤣).. I don't know..!🤔
 *
 * Okay, Steps for the hell?
 *  1. Select the HTML comment Node via browser selector (where `contentEditable = true`)
 * `2. paste the code
 *  3. run following codes
 *     a = AutoComment(); //Optionally it accepts the comment node as first argument, you can skip if you've selected the html input node by selection tool.
 *     a.startComment(); // startComment() takes 2 optional parameters. first arg for noOfComments (Default 100) and 2nd arg for interval (default 1500ms). If you set interval less, Facebook may block your account. Keep interval large
 *  4. That's all.
 *
 *  5. If you want to stop the comment in middle of the process just call `a.stopComment()
 *

 *
 * Oh man, this is not user friendly, have to do lot of stuff...
 * --- I don't care 😑. normal user don't open console or developer tool. If normal user needs this type of script, browser extension is the possible solution
