JavaScript Error: ReferenceError: getVersion is not defined - Solution

The error message 'ReferenceError: getVersion is not defined' indicates that your code is attempting to use a function named 'getVersion' that hasn't been defined yet. This could be due to a few reasons:

1. Missing Code or Library: The code defining the 'getVersion' function might be missing or not properly included. Ensure you have the necessary library or code snippet that defines this function.
2. Typographical Error: Double-check if there's a typo in the function name. JavaScript is case-sensitive, so 'getVersion' is different from 'getversion'.
3. Function Scope: If the 'getVersion' function is defined within a different scope (like inside a conditional statement or function), it won't be accessible from the current scope. Ensure the function is defined in a scope where it can be reached.

To resolve this error:

1. Include the necessary code or library: If the 'getVersion' function belongs to a specific library, make sure you've included it correctly in your script.
2. Define the function yourself: If it's a custom function, define it before attempting to call it. For example:

function getVersion() {
  // Function logic here
}

3. Verify function name and scope: Carefully check for typos in the function name and ensure that the function is accessible from where you're trying to use it.

Once you've defined or included the 'getVersion' function correctly, the error should be resolved.
