Using Catch and CatchAll decorator to wrap method or class with try catch with an error and handler

Class

@Catch(Error, handlerFunction)
Class A{
	method(){
			throw new Error()
	}
}

function handlerFunction(error: Error, ctx){
	console.log(error)
}

Using withTryCatch to wrap a function

function divide(a: number, b: number): number {
  if (b === 0) {
    throw new Error("Cannot divide by zero");
  }
  return a / b;
}

const safeDivide = withTryCatch(divide);

console.log(safeDivide(10, 2)); // 5
console.log(safeDivide(10, 0)); // Error: Cannot divide by zero
