Please someone check this code for me and tell me what's wrong?

Question

function exercice1(chiffre) {
(chiffre === 0) ? 'zéro':
(chiffre ===1) ? 'un':
(chiffre === 2) ? 'deux';
}

Answer 1

Either use return keyword with if else statement or use turnery operator .

Ex. If (condition)
{ return value ;}
Else{return value;}

Or

If(condition)? return value if true :return value if false;

Answer 2

You have to add return for a function in order to get the returned value

function exercice1(chiffre) {
return (chiffre === 0) ? 'zero':
(chiffre === 1) ? 'un':
(chiffre === 2) ? 'deux':
null; // null for chiffre >2
}

console.log(exercice1(0))
console.log(exercice1(1))
console.log(exercice1(2))

Answer 3

In Es6:

const exercice1 = chiffre =>
(chiffre === 0) ?'zéro'
:(chiffre === 1) ?'un'
:(chiffre === 2) ?'deux'
:"???";

for(let i=0; i<=3; i++)
console.log(exercice1(i));

Answer 4

If you are checking for only three conditions; then remove the last tenary operator. Something like this 👇;

function exercice1(chiffre) {
(chiffre === 0) ? 'zéro':
(chiffre ===1) ? 'un': 'deux';
}

The last line (chiffre===2)?'deux';
must have two values 'deux' : ... ;
whereas you provided only one

Or you can simply create an array like this 👇
var numbre =["zero", "une", "deux",....];

and in the function; maybe you are returning the number in words; you do

return numbre[chiffre];
