@Dnouv It's ready to merge. Here is the preview, and I have defined the proper prop types which are required for good developer experience.

• The output is in text/HTML which can be directly used
• Editing old data is also available. The developer just needs to pass an optional prop i.e [value]
• Plug & Play component with 4 parameters i.e onChange, value, placeholder, and name
