Here's the challenge:
Create a function makePlans that accepts a string. This string should be a name. The function makePlans should call the function callFriend and return the result. callFriend accepts a boolean value and a string. Pass in the friendsAvailable variable and name to callFriend.
Create a function callFriend that accepts a boolean value and a string. If the boolean value is true, callFriend should return the string 'Plans made with NAME this weekend'. Otherwise it should return 'Everyone is busy this weekend'.>
Here's what I wrote:
let friendsAvailable = true;
function makePlans(name) {
return callFriend(friendsAvailable, name);
}
function callFriend(bool, name) {
if (bool = true) {
return 'Plans made with ' + (name) + ' this weekend'
} else {
'Everyone is busy this weekend'
}
}
console.log(makePlans("Mary")) // should return: "Plans made with Mary this weekend'
friendsAvailable = false;
console.log(makePlans("James")) //should return: "Everyone is busy this weekend."Besides the if (bool = true) part that everyone has already pointed out (you could use if (bool) for this), you forgot to add return in else statement. It should be:
} else {
return 'Everyone is busy this weekend'
}
Complete code:
let friendsAvailable = true;
function makePlans(name)
{
return callFriend(friendsAvailable, name);
}
function callFriend(bool, name)
{
if (bool) // or if (bool===true), but testing if true is true is a little bit redundant
{
return 'Plans made with ' + (name) + ' this weekend'
}
else
{
return 'Everyone is busy this weekend'
}
}
console.log(makePlans("Mary")) // should return: "Plans made with Mary this weekend'
friendsAvailable = false;
console.log(makePlans("James")) //should return: "Everyone is busy this weekend."But if you want to impress your teacher do this:
const
callFriend =
(bool, name) =>
bool
? `Plans made with ${name} this weekend`
: 'Everyone is busy this weekend'
const makePlans = name => callFriend(friendsAvailable, name);
let friendsAvailable = true
console.log(makePlans('Mary'))
friendsAvailable = false
console.log(makePlans('James')) some helpers:
