No offence
Can you give an example of the multi nested functions? I was a TS dev for a while and don’t remember anything like that. Unless you mean the promise callback functions. Those were a mess but luckily we’ve mostly moved away from those
People creating functions as objects inside of other functions. A few days ago saw a person create a function with two object functions inside, then passed one of the functions as an argument to the other function. Then returned the second function.
It’s hard to find such a mess in other languages. Yeha, functions as objects are cool. Closures are also cool… But why abuse that shit?
