Dog Years – JavaScript Project

Published on

Here is another javascript project after Kelvin weather, the calculation of Dog years in javascript.

Dogs mature at a faster rate than human beings. We often say a dog’s age can be calculated in “dog years” to account for their growth compared to a human of the same age. In some ways we could say, time moves quickly for dogs — 8 years in a human’s life equates to 45 years in a dog’s life.


How old would you be if you were a dog?

Here’s how you convert your age from “human years” to “dog years”:

  • The first two years of a dog’s life count as 10.5 dog years each.
  • Each year following equates to 4 dog years.

By using JavaScript here is how to convert your human age into dog years.

// My age which is counted as human years.
const myAge = 28;

// The first 2 years of dog.
let earlyYears = 2;

// The calculation of early 2 years of dog.
earlyYears *= 10.5;

// The later years of dog.
let laterYears = myAge - 2;

// The calculation of later years of dog.
laterYears *= 4;

// My name and that too in lowercase.
const myName = "Atul".toLowerCase();

// Summing the dog years combining their early and later years.
const myAgeInDogYears = earlyYears + laterYears;

// Outcome.
console.log(`My name is ${myName}. I am ${myAge} years old in human years which is ${myAgeInDogYears} years old in dog year.`);

In the last line, I have used the backtick not the apostrophe symbol, do remember that.

The outcome of the above code should be:

My name is atul. I am 28 years old in human years which is 125 years old in dog year.

That’s how we have completed another javascript project for calculating a dog’s age.
