The JavaScript language as a format is free to use for everyone, and the use of JavaScript in a website is not that actually bad. However, it can be bad if the JavaScript program is not free to sue. Take note that when the website transfers a program to the user, it is not sufficient for the program to be put down in an unencumbered and documented language, that program should also be free. “Transmits only free of charge programs to the user” is mandatory to be part of the criterion for an honest and ethical website.
