Return arrays must be of arraytype

by

When you encounter the error “return arrays must be of arraytype,” it means that you are trying to return a value that is not an array, but should be.

Here’s an example to better understand this error:

function getNumbers() {
  return 123; // Instead of returning an array, this function is returning a number
}

const numbers = getNumbers(); // Calling the function
console.log(numbers); // Output: Uncaught TypeError: return arrays must be of arraytype

In the above example, the function getNumbers() is expected to return an array of numbers, but it is incorrectly returning a number (123) instead. As a result, when we try to assign the return value of the function to numbers and log it, we get the error “return arrays must be of arraytype.”

To fix this error, you need to ensure that the function is returning an array. Here’s an updated example:

function getNumbers() {
  return [1, 2, 3]; // Now the function returns an array
}

const numbers = getNumbers();
console.log(numbers); // Output: [1, 2, 3]

In the updated code, the function getNumbers() now correctly returns an array [1, 2, 3]. When we call the function and log the value of numbers, we no longer encounter the error.
