There are exceptions when I use JS. When I have to use someone else's computers or manage certain accounts using the www. The later not being by choice.
In the 90's, there was an attempt to allow web developers to run their code on the user's computer via the user's web browser. This was called Java applets.
There was no limit to the pie-in-the-sky promises that developers were making back then. All based around the web browser and Java.
Not surprisingly, Java applets failed. I think there were some security issues. Maybe. Not sure.
Javascript reminds me of Java applets.
I am not sure if there are security issues with Javascript. From discussion surrounding this language, today we are asked to believe there is nothing that cannot be accomplished with a web browser and some Javascript. Unlike Java applets, this time, it is real. I think.
But, as far as I know, I too can do anything I want to do without using Javascript. And without using Java applets. If there are websites that truly require Javascript (see below) in order to access data, I cannot find them.
1. require
Here, "require" means that the data could not be served to the user via any other e.g. more direct mechanism than through a series of steps that includes Javascript being run by a web browser. Here, "require" does not mean the choice by the website owner to use Javascript in this way or a message displayed to users that suggests "Javascript is required". The meaning here refers to technical capabilities not design choice.
