Obtain All the array name that are tiny from a JavaScript array-CodePudding

I Have an array name friends. I want to print all the (not single) name which are tiny from this array. How i can solve it??:

function tinyFriend(friends) {
    let tinyFriend = friends[0]
    for (let i = 0; i < friends.length; i  ) {
        let element = friends[i]
        if (tinyFriend.length>element.length) {
            tinyFriend = element
           }

    }
    console.log("The Smallest Name is",tinyFriend)
}

let friends = ["kamal","shak","shak","shakib", "brac"]
tinyFriend(friends)

my expected result is shak,shak,brac

you basically need to make tinyFriend an array, and add some logic like:

is the current name the same length as the one being checked? if so add it to the array
is the checked name smaller than the current name(s)? in that case overwrite the array

function tinyFriend(friends) {
    // put the first name in an array to begin..
    let tinyFriends = [friends[0]];
    
    // loop the names in the array
    for (let i = 0; i < friends.length; i  ) {
        let element = friends[i]
        
        // check if same length and add to array if so
        // notice we now check against the first item in the tinyFriends array
        if (tinyFriends[0].length === element.length) {
          tinyFriends.push(element);
        
        // else if the checked name is shorter, replace the array 
        } else if (element.length < tinyFriends[0].length) {
          tinyFriends  = [element];
        }
    }
    
    // remember, since we now output an array, we might need to handle it differently
    console.log("The Smallest Name is", tinyFriends)
}

let friends = ["kamal","shak","shak","shakib", "brac"]
tinyFriend(friends)

You need to be able to store the names somewhere that match the critera - ie in an array.

But it might be easier to find the minimum name length first and then filter out the names whose length match that value.

function tinyFriend(friends) {

  // `map` over the array and return an array of name lengths
  // then use `Math.min` to determine the smallest value
  // in that array. `Math.min` expects a list of arguments
  // so we use the spread syntax on the array
  const min = Math.min(...friends.map(name => name.length));

  // Now `filter` out the names whose length matches that value
  return friends.filter(name => name.length === min);

}

let friends = ['kamal', 'shak', 'shak', 'shakib', 'brac'];
console.log(tinyFriend(friends));
