const secsPerMin = 60;
const minsPerHour = 60;
const hoursPerDay = 24;
const daysPerWeek = 7;
const weeksPerYear = 52;
const secondsPerDay = secsPerMin * minsPerHour * hoursPerDay;
console.log(`There are ${secondsPerDay} seconds in a day.`);
const yearsAlive = 32;
console.log(`I've been alive for more than ${yearsAlive * weeksPerYear * daysPerWeek * secondsPerDay} seconds!`);

3,875 PointsThis is what i came up with.
const secsPerMin = 60; const minsPerHour = 60; const hoursPerDay = 24; const daysPerWeek = 7; const weeksPerYear = 52;
const secondsPerDay = secsPerMin * minsPerHour * hoursPerDay;
console.log(There are ${secondsPerDay} seconds in a day.);
let yearsAlive;
console.log(I've been alive for more than ${+86400 * +7 * +52 * +31} seconds!);

231,248 PointsI think the idea was to use the constants and not replicate the literal values. Also, what are the "+" symbols for?
benoit koch
3,875 PointsAll good :) Oh, i think it was a mistake on my part, i was thinking for some reason that the system would read it as a string, so i added some precautions but i don't think that would of affected the conclusion. + is the quick form of parseInt. "The parseInt() function parses a string and returns an integer."

console.log(I've been alive for more than ${+86400 * +7 * +52 * +31} seconds!);
