A tags input is a user interface (UI) component that allows the user to add or insert multiple entries as tags into an input field. In this project (Tags Input in JavaScript), as you can see on the webpage, there is an input box with some tags, buttons, and tags counters.You can remove each tag by clicking on a close icon or remove all tags at once by clicking on the Remove All button. You can insert a maximum of the limit of tags only and duplicate tags won’t be added in the input field or both are in your control.Well, this is a vanilla JavaScript-based tags input component that stores the typed tags in a hidden input field. Type something in the input and then press Enter or Comma key to add a new tag. Click the X button or press the Backspace button 2 times to delete the tag.There are many code snippets available online or on many other blogs and websites but everyone is not able to optimize your blog or website so you need some optimized code snippet.
