JavaScript Array Elements Divided into Separate Arrays

I am struggling with a function that is supposed to accept an array as parameters and then log all the elements of the array into a single new array. However, the issue I am facing is that each array element is being printed separately instead of combined into one array. Here is my code:

const result = []
function combineArrayElements(arr){
    //your code here
    for (let i = 0; i < arr.length; i++) {
        const element = arr[i];
        console.log(new Array(element))
    }
}

combineArrayElements("AAAA") \\ is printing ['A'], ['A'], ['A'], ['A']
\\ Instead of ['A', 'A', 'A', 'A']


Answer №1

In order to complete this task, you must first initialize an Array object and then proceed to insert the values within a loop. Once the loop has ended, ensure to use a Console.log statement to display the final result.

const output = []
    function convertLetters(str) {
        //Add your code here
        let array = [];
        
        for (let j = 0; j < str.length; j++) {
            const entry = str[j];
            array[j] = entry;
        }
        
        console.log(array)
    }

    convertLetters("ABCD"); 

Answer №2

A better approach than iterating through an array is to utilize either Array.from() or .split('')

function DNASequence(dna){

        console.log(Array.from(dna))

  }

  DNASequence("AAAA")

Alternatively,

function DNASequence(dna){

        console.log(dna.split(''))

  }

  DNASequence("AAAA")
