Get rid of those dumb decisions and it could have been pure JS and be 100% fine. C has no value here. The slow performance of JS is not harmful here. Discord is fast enough although it's Electron. VS Code is also fast enough.
But I'd also like to respond to the food analogy, since it's funny.
Let's say that going full untyped scripting language would be the fast food. You get things fast, it does the job, but is unhealthy. You can write only so much bash before throwing up.
Developing in C is like cooking for those equally dumb expensive unsustainable restaurants which give you "an experience" instead of a full healthy meal. Sure, the result uses the best ingredients, it's incredibly tasty but there's way too little food for too much cost. It's bad for the economy (the money should've been spent elsewhere), bad for the customer (same thing about money + he's going to be hungry!) and bad for the cook (if he chose a different job, he'd contribute to the society in better ways!) :D
Just go for something in the middle. Eat some C# or something.
