JavaScript Code

Problem Statement

given an array of strings, write a JavaScript program to find the shortest string in array

Solution

to find the shortest string in the given array of strings using JavaScript,

• initialize the shortest with the first string in array
• iterate over items of the array using a for loop
  • if the current element is smaller in length than that of the shortest, update shortest with the current element

we use

• String.length to get the length of a string
• greater than comparison operator to check if the length of shortest is greater than the length of the current element in array

Program

1. given array of strings is strArray. find the shortest string

function findShortestString(arr) {
  let shortest = "";
      if (arr.length == 0) {
          return null;
      } else {
          shortest = arr[0];
          for (let i = 1; i < arr.length; i++) {
              if ( shortest.length > arr[i].length ) {
                  shortest = arr[i];
              }
          }
          return shortest;
      }
}

strArray = ["apple", "banana", "bean", "pineapple"];
shortest = findShortestString(strArray);
console.log(shortest);
