I have the following object:
var car = {
doors: 4
wheels: 4
}
This is used in many files, is there a way that it can be checked easily across the entire codebase?
function insertCar(car) {
if (!isCar(car)) {
console.log('not a car')
}
}
If I understood you correctly, instaceof will be the answer. You can do something like this:
function Car(make, model, year) {
this.make = make;
this.model = model;
this.year = year;
}
var mycar = new Car('Honda', 'Accord', 1998);
var a = mycar instanceof Car; // returns true
var b = mycar instanceof Object; // returns true
As for exporting and importing, you need to define your object in one file and export it:
module.exports = function Car(make, model, year) {
//...
}
Then you import it in whichever file you want with
import Car from 'components/car'
where components/car is an example of your file where object Car is exported from, in this case Car.js which is located in directory components.
instanceof Car to be used across files?
