How to solve "Uncaught TypeError: e.slice is not a function"?

 This error typically occurs when you try to use the slice() method on a variable that is not an array or string. The slice() method is only available for arrays and strings, so if you try to use it on any other data type, you will get this error.

To fix this error, you should first check the type of the variable e to make sure that it is an array or string before using the slice() method on it. Here is an example:

if (typeof e === 'string' || Array.isArray(e)) {
  var sliced = e.slice(0, 5); // call slice() method on e
  console.log(sliced);
} else {
  // handle the case where e is not a string or array
}

In this example, we check whether e is a string or an array using the typeof and Array.isArray() methods. If e is a string or an array, we can safely use the slice() method on it. If e is not a string or an array, we should handle the error appropriately.

Note that the slice() method returns a new array or string that contains the selected elements, so you need to assign the result of the slice() method to a new variable.
