Js return property

Get Help JavaScript
#1

Hey guys. I’m currently working on the Training Days Javascript lesson. Below is the code that I am looking at:

// The scope of random is too loose
const random = Math.floor(Math.random() * 3);

const getRandEvent = () => {
if (random === 0) {
return ‘Marathon’;
} else if (random === 1) {
return ‘Triathlon’;
} else if (random === 2) {
return ‘Pentathlon’;
}
};

// The scope of days is too tight
const getTrainingDays = event => {
let days = 50;
if (event === ‘Marathon’) {
} else if (event === ‘Triathlon’) {
} else if (event === ‘Pentathlon’) {
}

My question is how did the getTrainingDays() event parameter get the value of Marathon, Tirathlon, and Penathlon? Doesn’t the return property in the getRandEvent() return those values to the caller?

#2

it does, so you pass the result of calling getRandEvent to getTrainingDays:

getTrainingDays(getRandEvent());

or you can do this with intermediate steps.
