Is my code correct?

Just curious if my code is correct.

Please check out my work. I'm curious if I had made any mistakes.

I haven't checked out any other discussion questions as I didn't want to see other codes to make myself want to change my code.

Here is my snapshot. https://w.trhou.se/ljc6suqtj1

It's fine as it is (good job! :+1:), but since you already computed "secondsPerDay", you could take advantage of that to make the final calculation a bit more concise:

var daysAlive = secondsPerDay * daysPerWeek * weeksPerYear * yearsAlive;

Also, while technically optional, it's good practice to always end a statement with a semicolon.

Oh yeah, you're completely right. I totally disregarded secondsPerDay. And yes I ended up looking at my post right after I posted it and noticed I didn't have a semicolon. Luckily someone pointed it out. :)

var secondsPerMin = 60; var minsPerHour = 60; var hoursPerDay = 24; var daysPerWeek = 7; var weeksPerYear = 52; var secondsPerDay = secondsPerMin * minsPerHour * hoursPerDay; document.write ('There are ' + secondsPerDay + ' seconds in a day'); var yearsAlive = 32; var socondsAlive = secondsPerMin * minsPerHour * hoursPerDay * yearsAlive; document.write('. I have been alive for more than ' + socondsAlive + ' seconds. '); //How about this guys? Am I correct? Please someone check it out ?

It looks like your final calculation is missing some factors.

But always create a fresh question instead of posting a question as an "answer" to another one.
