Syntax error Get the longest and shortest string in an array JavaScript

Get the longest and shortest string in an array JavaScript

We have an array of string literals like this −

const arr = ['Some', 'random', 'words', 'that', 'actually', 'form', 'a',
'sentence.'];

We are required to write a function that returns the longest and the shortest word from this array. We will use Array.prototype.reduce() method to keep track of the longest and shortest word in the array through a complete iteration.

The code for this will be −

Example

const arr = ['Some', 'random', 'words', 'that', 'actually', 'form', 'a',
'sentence.'];
const findWords = (arr) => {
   return arr.reduce((acc, val) => {
      const { length: len } = val;
      if(len > acc['longest']['length']){
         acc['longest'] = val;
      }else if(len < acc['shortest']['length']){
         acc['shortest'] = val;
      };
      return acc;
   }, {
      longest: arr[0],
      shortest: arr[0]
   });
};
console.log(findWords(arr));

Output

The output in the console will be −

{ longest: 'sentence.', shortest: 'a' }
