How do I create sub-calls in Javascript functions?
Below is an example of use, my question is how to create such a function. Depending on what happens inside the "Travel" routine, the call is called "Arrival" and / or "Problem"
this.Viajar('são paulo').Chegada(() => {
console.log('chegou com sucesso')
}).Problema(() => {
console.log('pneu furou')
});
What you are referring to are not really functions, they are classes, where classes have methods inside them, see below:
class Ponto {
constructor(x, y) {
this.x = x;
this.y = y;
}
static distancia(a, b) {
const dx = a.x - b.x;
const dy = a.y - b.y;
return Math.sqrt(dx*dx + dy*dy);
}
}
const p1 = new Ponto(5, 5);
const p2 = new Ponto(10, 10);
console.log(Ponto.distancia(p1, p2));
You can create classes to manipulate values, with predefined functions to handle their elements. Check out other apps at: link
