JavaScript Code:

function max_of_three(x, y, z) 
 {
  max_val = 0;
  if (x > y)
  {
    max_val = x;
  } else
  {
    max_val = y;
  }
  if (z > max_val) 
  {
    max_val = z;
  }
  return max_val;
}

console.log(max_of_three(1,0,1));
console.log(max_of_three(0,-10,-20));
console.log(max_of_three(1000,510,440));

Sample Output:

JavaScript: Tips of the Day

Classes/function constructors

class Person {
  constructor() {
    this.name = 'Owen';
  }
}

Person = class AnotherPerson {
  constructor() {
    this.name = 'Eddie';
  }
};

const member = new Person();
console.log(member.name);

We can set classes equal to other classes/function constructors. In this case, we set Person equal to AnotherPerson. The name on this constructor is Eddie, so the name property on the new Person instance member is "Eddie".
