SyntaxError: Unexpected token { when trying to export a class in es5 module for use in another module

Question

Any ideas how the error is occuring? The class looks to be declared ok ..

car.js

function Car() {}

Car.prototype.setNumberOfWheels(numberOfWheels) {
    this.numberOfWheels = numberOfWheels;
}

Car.prototype.print() {
    console.log(this);
}

module.exports.Car = Car;

server.js

const model = require('./model.js');

Error:

Car.prototype.setNumberOfWheels(numberOfWheels) {
                                                ^

Answer 1

You should declare setNumberOfWheels and print as a functions.

Car.prototype.setNumberOfWheels = function(numberOfWheels) {
    this.numberOfWheels = numberOfWheels;
}

Car.prototype.print = function() {
    console.log(this);
}
