One line of JS, no looping:
console.log(a.concat(a.splice(0,k).join(' ')));
.join(' ') goes one parentheses out hehe
console.log(a.concat(a.splice(0,k)).join(' '));
aaah - good call on not using loops! I updated my ruby version to just work with arrays directly.
whats 'k'?
Yeah not sure what k is here
One step forward with spread operator:
return [...a.splice(d, a.length - 1), ...a];
And simplified:
return [...a.splice(d), ...a]
Arrays: Left Rotation
