I'm wondering if there's a way to reference the "current class" rather than a class by name, from within a Javascript class.
For example:
class MyBase{
static makeNew(id){
const newInstance = new --currentClass--;// magic happens here
newInstance.id = id;
return newInstance;
}
}
class A extends MyBase{}
class B extends MyBase{}
const newA = A.makeNew(1);
const newB = B.makeNew(379);
Is there a way for me to write MyBase::makeNew in such a way that when it's called from the A class, it returns a new instance of A, but when called from the B class, it returns a new instance of B?
Since the call signatures are like:
A.makeNew(1);
B.makeNew(379);
That might look familiar - you can use this to reference the object it's being called on.
class MyBase{
static makeNew(id){
const newInstance = new this();
newInstance.id = id;
return newInstance;
}
}
class A extends MyBase{}
class B extends MyBase{}
const newA = A.makeNew(1);
const newB = B.makeNew(379);
console.log(newA instanceof A);
console.log(newB instanceof B);
