If you missed the introductory post, it's here. For a list of previously solved katas, please refer to the bottom of this page.
If this is your first time seeing my post, please note - these katas are probably randomly assigned per user so please don't go into Codewars thinking we will have exactly the same user experience, I am just posting these in the order that I got them.
Kata #20
DESCRIPTION:
Complete the solution so that it reverses the string passed into it.
'world' => 'dlrow'
'word' => 'drow'
Starting code:
function solution(str){
}My attempt (loving the one-liner club!):
const solution = str => str.split('').reverse().join('')Rank #1 in 'Best Practice':
function solution(str){
return str.split('').reverse().join('');
}Rank #2:
const solution = str => str.split('').reverse().join('');Rank #3 with an example of how to use the spread operator:
const solution = s => [...s].reverse().join('')Rank #4 on how to do it with a for loop:
function solution(s){
var o = '';
for (var i = s.length - 1; i >= 0; i--)
o += s[i];
return o;
}That's it for Kata #20, stay tuned for more katas to be solved!
