Question

Is there a way to divide a string and insert something into the new array that is created?

I am facing an issue with adding a new fruit to a string that is converted into an array. Here's the scenario:

var fruits = "banana,apple";

In an attempt to add a new fruit to this list, I tried converting it to an array and then using the push method like so:

var newFruit = "orange";
fruits
  .split(",")
  .push(newFruit);

However, I encountered a problem because when I split fruits using ",", it doesn't return a standard array which allows me to use the push() function on it.

Is there a workaround for achieving this desired outcome?

Answer №1

split function does indeed return a standard array. It appears that you are effectively using the push method on it.

However, the issue arises when you discard the array after pushing elements to it, rendering it inaccessible for any further operations.

Given that push function doesn't return the modified array itself, there is no way to manipulate or work with the array post pushing new elements into it.

concat function, on the other hand, generates and returns a new array containing the combined values, but still requires additional steps to utilize this new array effectively.

var fruits = "banana,apple";
var newFruit = "orange";
var myArray = fruits
  .split(",")
  .concat(newFruit);
console.log(myArray);

Array.prototype.push will return the updated length of the array:

Result:

The updated length property of the object on which the method was executed.

MDN Reference

In addition, make sure to store your new value after using push. Here's an example of how you can do it:

var fruits = "apple,banana";
var newFruits = fruits.split(","); // Save the new array
newFruits.push("orange"); // Add the new item

console.log(newFruits);

If you prefer doing it in a single line, you can use concat:

var fruits = "apple,banana";
var newFruits = fruits
      .split(",")         // Transform string to array
      .concat("orange");  // Generate a new array combined with the value

console.log(newFruits);

When using the push method, it returns the new length of the array. If you do not save this result, you will not be able to see the updated array after pushing a new value into it. To ensure you can access the updated array, consider splitting the original array and then pushing the new element in two separate lines:

newFruits = fruits.split(",");
newFruits.push(newFruit);
