TIL array.at()

Another small function I just learned about. myArray.at(x) works almost like myArray[x]. But the new .at() method has one awesome advantage. It supports negative indices which lets you access an array from the end. Negative indices with the conventional method would result in undefined

const myArray = [  
  'Banana',  
  'Apple',  
  'Mango',  
  'Pineapple'  
]

console.log(myArray.at(-1)) // will result "Pineapple"

Unfortunately Safari doesn't support the .at() method yet. But what did I expect? 😫
