I'm a big fan of final/sealed in every language and the stronger contract it allows, but I think the existing support is nearly sufficient - the example in TypeScript handbook | Class Decorators: function sealed(constructor: Function) { Object.seal(constructor); Object.seal(constructor.prototype...

expects the type to always be non-null, which can never be truly asserted in JavaScript. A user might define something like this: function(myNonNull:!myClass):void { myNonNull.foo(); } And because it's defined as non-null, everything might be happy for the compiler, but then someone...

Is there some way we can avoid the possibility of a null reference in the first place? Today we’ll go searching for such a mythical type. Let’s write a very simple function in C#: voidDoDamage(Weapon weapon, Player target){target.Health-=weapon.Damage;} ...
functiondoSomething(callback?:()=>void) {// Error: Object is possibly 'undefined'.callback();} Similar to checking objects before accessing a property, we need to check first whether the function has a non-null value: functiondoSomething(callback?:()=>void) {if(callback) {callback();...
