As a dev who primarily works in JS, I'm extremely curious to hear about this! When I talk about limitations of JS, I point out the shortcomings (lack of native 64-bit integer support, or anything other than its singular "number" type is a big one), their workarounds, then conclude by saying it will probably be addressed in the future. The ecmascript standards are very well specified, and compatibility is well mapped out.
Are you talking about node.js by chance? I'm confused about what was "installed" and what options were available. Normally js runs in a browser, and there's not much in the way of options when installing those. Are you talking about the language itself, or the environment such as npm modules?
I like to criticize c# myself, but I think the complaints more accurately pertain to the .net framework.
Please share some details, because I love to know about JS caveats and pitfalls and share them with others. Without this information, they sound like pebkac issues.
Wishing for JS to die out is for wusses. Why not be proactive about killing it off with a better alternative for browser providers to implement? What would you suggest? Samsung has a lot invested in their Tizen OS, and they're not about to abandon that any time soon.
