As I embark on my journey with Angular 2 and TypeScript, one concept that has me a bit puzzled is how to implement callback functions. I understand that this might be a basic question, but when I look at this typical JavaScript code:
someOnject.doSomething('dsadsaks', function(data){
console.log(data);
});
I find myself wondering, what would be the TypeScript equivalent?
In TypeScript, the identical code functions as expected. Another option is to utilize
someOnject.performAction('dsadsaks', response => {
console.log(response);
});
One distinction is that in the second iteration, this. will point to the encompassing class.
This code snippet demonstrates a valid use case in a TypeScript environment. You have the option to enforce strong typing on your function inputs as well:
const message:string = 'dsadsaks'
someOnject.doSomething(message, data:string =>{
console.log(data);
});
