If within a class constructor and I lookup an object that contains many values, how can I make it so that class will obtain all those values?
For example, if this is my object:
const myObject = {
a: 1,
b: 2,
c: 3
}
This is my class:
class MyClass {
constructor() {
const object = createMyObject(); // This function returns the above myObject
}
}
Now, how do I make it so MyClass has all the values of myObject so I can do something like:
const class = new MyClass();
console.log(class.a);
// 1
you can do this:
function createMyObject(){
return {
a:1,
b:2,
c:3
}
}
class MyClass{
constructor(){
Object.assign(this,createMyObject())
}
}
const res = new MyClass();
console.log(res.a)
console.log(res.b)
console.log(res.c)Iterate over the object with Object.entries and assign the key/value pairs to the class.
function createMyObject() {
return {
a: 1,
b: 2,
c: 3
};
}
class MyClass {
constructor() {
const object = createMyObject();
const entries = Object.entries(object);
for (const [key, value] of entries) {
this[key] = value;
}
}
}
const o = new MyClass();
console.log(o.a);
console.log(o.b);
console.log(o.c);
