Question

I'm seeking some assistance in resolving my JavaScript issue

Let's create a function known as 'bigOrSmall' that requires one parameter, 'arr', which will contain an array of numbers. Inside the 'bigOrSmall' function, let's define a new array named 'answers'. Next, iterate through the input arr parameter and determine if each number in the array is greater than 100. If the number exceeds 100, add 'big' as a string to the answers array. Alternatively, if the number is less than or equal to 100, append 'small' as a string to the answers array. Finally, return the answers array within the function.

This represents my current progress.

function bigOrSmall(answers) {
    for(let i = 0; i > 100; i++) {
        return answers('big')
        if(let i = 0; i <= 100; i++) {
            return answers('small')
        }
        answers(arr[i])
    }
    return answers,
}

It seems like there might be an issue with my implementation since it's not passing the test. I am eager to receive some guidance on how to improve and move forward in the right direction.

javascript arrays function for-loop

Answer 1

Answer №1

When you're inside the loop, utilizing return will end the function during the initial iteration.

To optimize your code, consider the following:

function checkSize(arr) {
  const responses = [];
  for(let i = 0; i < arr.length; i++) {
    if (arr[i] <= 100) {
      responses.push('small');
    } else {
      responses.push('big');
    }
  }
  return responses;
}

console.log(checkSize([0, 105, 100]))

You also have the option to utilize Array.map() for a more concise solution

const mappedResponses = [0,105,100].map(item => item <= 100 ? 'small' : 'big')

console.log(mappedResponses)

I regret to inform you that there are some errors in your current approach. Let's analyze the code snippet provided below together, which will offer insights on how to rectify these mistakes (carefully read the comments):

// creating a function called bigOrSmall with parameter 'arr'
function bigOrSmall(arr) { // pay attention to the parameter `arr`
    let answers = []; // initializing an array named `answers`
    for(let i = 0; i < arr.length; i++) { // looping through the elements of array `arr` using index
        if(arr[i] > 100) { // checking if the value at index i in array `arr` is greater than 100
            answers.push('big'); // adding 'big' to the `answers` array
        } else { // if not
            answers.push('small'); // adding 'small' to the `answers` array
        }
    }
    return answers; // returning the `answers` array
}

let someIntegers = [1, 2, 300, 40, 229, 100]; // defining an array of integers

let ans = bigOrSmall(someIntegers); // invoking the `bigOrSmall` function with `someIntegers` as input and storing the returned array in variable `ans`
// note: The array `someIntegers` is passed as `arr` inside the `bigOrSmall` function

console.log(ans); // displaying the output array

The resulting output of the program is:

[ 'small', 'small', 'big', 'small', 'big', 'small' ]

  function categorizeNumbers(arr) {
     const result = []; 
            for(let i = 0; i < arr.length; i++) {
               if (arr[i] <= 100) {
               result.push('small');
            } else {
              result.push('big'); 
            }
        }
        return result;
    }

Initially, the input should be an array of numbers, hence the parameter named 'arr'. Next, you create an empty array called 'result' to store categorized values. Iterate through the array and compare each number to 100, pushing 'small' or 'big' into the 'result' array accordingly. This logic can also be achieved using map or forEach method for better readability.

     const result = [];

               if (arr[i] <= 100) {
               result.push('small');
            } else {
              result.push('big'); 
            }
        }
        return result;
    }

this seems like a good solution worth testing.

function determineSize(answers){

      var isSmall = true;
      answers.forEach(item => {
        (item <= 100) ? isSmall = true : false;
      });
      (isSmall == true) ? answers.push('big') : answers.push('small');
      return answers
}
