canJump.js

const canJump = function(nums) {
  let len = nums.length;
  let max = 0;
  for (let i = 0; i < len; i++) {
    if (i > max) return false;
    max = Math.max(max, i + nums[i]);
  }
  return true;
};

console.log(canJump([2,3,1,1,4])); // true
console.log(canJump([3,2,1,0,4])); // false
console.log(canJump([2,3,1,1,4])); // true
