The code provided is incomplete and does not appear to contain any issues or irregularities that need to be checked for. It defines two methods, updateOrCloneAsset and methods, but it lacks the implementation of these functions. Additionally, the variable this seems to be undefined, which could cause problems during execution.

However, the main issue appears to pertain to how you handle the row.id parameter when updating an asset through the API using $route.params. You're currently assuming that the user will request one update ('update') after their last call. However, since this is just a placeholder in a more general function, there's likely no specific functionality related to the parameters being updated beyond making them available via this.$route.params.

In summary, given the current state of the code snippet here, it doesn't have any clear potential issues. For improvement/suggestion purposes:

• Please fully define and implement both the updateOrClonesAsset and methods functions.
• Ensure consistent referencing (i.e., use const instead of let where appropriate).
• Clarify the flow or purpose of accessing row.id based on what is supposed to happen with respect to the route updates.

Assuming all those steps are taken care of before attempting to run this piece of code again, I can't detect anything significant from its structure alone. The most direct action could be to add the missing implementation details needed to make these changes useful and then proceed with testing it further.

The difference between two files found is:

1. The first file has let values = _.cloneDeep(validValues) line that creates a deep clone of validValues object while the second does not use it to update data.

For optimization:

• Use `_.defaultsDeep(values, this.validValues || {});

• Make sure all objects in your project follow consistent formatting.

2. In both files, there are some unnecessary comments or extra spaces which makes code less readable but doesn't affect the flow of the logic.

As far as irregularities or potential issues go, I suggest reviewing the structure for any inconsistencies among variables or methods naming conventions used across components and controllers. You might find it useful to maintain consistency in variable names within each file's scope rather than global space usage where appropriate. Also consider making minor style improvements like trimming whitespace around operators and brackets.
