up vote 0 down vote favorite I'm looking to create a method for an object to update only the properties that are passed. for example function Car () { this.color = 'yellow' this.brand = 'bmw' this.key = 0 this.update = function (o) { this.key++ // maybe Object.assign(this, o) somehow ?? } } If I do Car.update({color:'red'}) I want to update the object but not overwrite the brand. I want to use something like Object.assign(this, o) but not sure how to assign it. Do I need to create a prototype? Car.prototype.update = ? javascript object methods prototype share | improve this question edited Nov 11 at 21:26 ...
