js constructor Person code example
Example 1: javascript constructor object
function Person(first, last, age, eye) {
this.firstName = first;
this.lastName = last;
this.age = age;
this.eyeColor = eye;
}
Example 2: why do we use Object Constructors
function Tree(name) {
this.name = name
}
let theTree = new Tree('Redwood')
console.log('theTree.constructor is ' + theTree.constructor)
