In the project I see that in the getTrainingDays function there are IF statements that evaluate IF event === a specific value and then sets days to a corresponding value. Where im not understanding is how does this code declare that event is equal to a perticular value anywhere? I get that we do a randevent return above, but I dont see how this sets the output of that event to a vairable called event. What am I missing here?
tl;dr: how does the getTrainingDays function know what event is if we arent assigning a value to something called event anywhere?
// The scope of `random` is too loose
const getRandEvent = () => {
const random = Math.floor(Math.random() * 3);
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;
if (event === 'Marathon') {
days = 50;
} else if (event === 'Triathlon') {
days = 100;
} else if (event === 'Pentathlon') {
days = 200;
}
return days;
};
// The scope of `name` is too tight
const name = 'Nala';
const logEvent = (name, event) => {
console.log(`${name}'s event is: ${event}`);
};
const logTime = (name, days) => {
console.log(`${name}'s time to train is: ${days} days`);
};
const event = getRandEvent();
const days = getTrainingDays(event);
// Define a `name` variable. Use it as an argument after updating logEvent and logTime
logEvent(name, event);
logTime(name, days);
const event2 = getRandEvent();
const days2 = getTrainingDays(event2);
const name2 = 'Warren';
logEvent(name2, event2);
logTime(name2, days2);
