Kata #34
DESCRIPTION:
This kata is about multiplying a given number by eight if it is an even number and by nine otherwise.
Starting code:
function simpleMultiplication(number) {
// your code........
}My attempt:
const simpleMultiplication = number => number % 2 === 0 ? number*8 : number*9Rank #1 in 'Best Practice':
function simpleMultiplication(n) {
return n * (n % 2 ? 9 : 8);
}Rank #2:
function simpleMultiplication(n){
return n % 2 == 0 ? n * 8 : n * 9
}Rank #3:
function simpleMultiplication(value){
if(value%2===0 ){
return value *8
}
else{
return value* 9;
}
}Rank #4:
const simpleMultiplication=n=>n*(n%2?9:8)That's it for Kata #34, stay tuned for more katas to be solved!
