Code Review - Javascript Math - How Many Seconds Have I Been Alive?

Hey, could anyone familiar with JS check my code is all good.. thanks!

const secspermin = 60;
const minperhour = 60;
const hourperday = 24;
const daysperweek = 7;
const weeksperyear = 52;

const secondsperday = secspermin * minperhour * hourperday;

const yearsalive = 26;

const secondsperyear = secondsperday * daysperweek * daysperweek * weeksperyear;

const secondsalive = secondsperyear / yearsalive;

console.log(` I've been alive for more than ${secondsalive} seconds.`);

Your code looks good, Gavin (nice spacing and naming of variables; your math is just a bit off). In your secondsperyear variable you're multiplying daysperweek twice (you should only be multiplying by that variable once). Also you're dividing secondsperyear by yearsalive, when you should be multiplying secondsperyear by yearsalive.

The way your code is currently, it's saying that you're 98 days old (8,467,200 seconds). But if you make those changes, you should get more accurate results.

Thank you Brandon, silly mistakes to make, I guess this shows the importance of properly checking your own code before posting 😂
