Hi,

I trust you are doing very well.

It is an Idea (https://success.salesforce.com/ideaView?id=08730000000cGX8AAM) to support Javascript Buttons in Lightning Experience.

However, you can use Lightning Experience Configuration Converter to convert JavaScript buttons to lightning. Please refer to the below links which might help you further with the above issue.

There are other options also to replace the javascript button in lightning. You can use Quick Actions, Custom Buttons, or Apex. Go through this trailhead module to understand the alternatives available:
Lightning Alternatives to JavaScript Buttons (https://trailhead.salesforce.com/en/modules/lex_javascript_button_migration)

Also, Please refer to the below links:

I hope it helps you.

Kindly let me know if it helps you and close your query by marking it as solved so that it can help others in the future.

Thanks and Regards,

I want to insert a lightning component to a visualforce page after a button click is done in the visualforce page. So I want to do some vf-controller functions and then open a lightning component in the apex controller of the vf page https://mybkexperience.me.
