I want to build a Vehicle class to create objects based on it. And I want to pass an object to the constructor function as a parameter such that const vehicle = new Vehicle({vehicleType: 'car', name: 'car1', range: 500})
I have built it like below but how can I destructure the constructor parameter in order to avoid repeating 'options.' word?
class Vehicle {
constructor(options = { vehicleType: 'car', name: '', range: '', seats: '' }) {
this.vehicleType = options.vehicleType
this.name = options.name
this.range = options.range
this.seats = options.seats
}
getRangeToSeatsRatio() {
return this.range / this.seats
}
multiplySeatsBy(count) {
this.seats *= count
return this
}
getSeatCount() {
return this.seats
}
get rangeToSeatsRatio() {
return this.range / this.seats
}
}
you can do it this way:
class Vehicle {
constructor(options) {
const { vehicleType = 'car', name = '', range = '', seats = '' } = options;
this.vehicleType = vehicleType
this.name = name
this.range = range
this.seats = seats
}
getRangeToSeatsRatio() {
return this.range / this.seats
}
multiplySeatsBy(count) {
this.seats *= count
return this
}
getSeatCount() {
return this.seats
}
get rangeToSeatsRatio() {
return this.range / this.seats
}
}
You can do it like this:
class Vehicle {
vehicleType = 'car';
name = '';
range = '';
seats = '';
constructor(options) {
Object.assign(this, options);
}
getRangeToSeatsRatio() {
return this.range / this.seats
}
multiplySeatsBy(count) {
this.seats *= count
return this
}
getSeatCount() {
return this.seats
}
get rangeToSeatsRatio() {
return this.range / this.seats
}
}
