(8 kyu) The Feast of Many Beasts.js

// 1 Plain Solution
function feast(beast, dish) {
  let result;
  const start = beast[0] === dish[0];
  const end = beast[beast.length - 1] === dish[dish.length - 1];
  
  result = start && end;
  
  return result;
}

// 2 Straightforward solution
function feast(beast, dish) {
  let result;
  const start = beast[0] === dish[0];
  const end = beast.slice(-1) === dish.slice(-1);
  
  result = start && end;
  
  return result;
}

// 3 Optimized solution
const feast = (beast, dish) =>
  beast[0] === dish[0] && beast.slice(-1) === dish.slice(-1);

// 4 Clever solution
const feast = (beast, dish) =>
  dish.startsWith(beast[0]) && dish.endsWith(beast.slice(-1));
