Cannot read property 'forEach' of undefined

Comment

//The "Cannot read property 'forEach' of undefined" error occurs when calling the forEach method on an undefined value.

//To solve the error make sure to initialize the variable to the correct value and only call the forEach method on the correct data type.

const arr = [];

arr[0]?.forEach(element => {
  console.log(element);
});
