getValueobjOrDefault

getValueobjOrDefault is a utility function, commonly found in programming libraries, designed to retrieve a value from an object while providing a default value if the specified key is not present or its corresponding value is null or undefined. This function aims to simplify the process of accessing potentially missing data, preventing runtime errors such as "TypeError: Cannot read properties of undefined" or "Cannot read property 'x' of null."

The typical signature for such a function involves three arguments: the object to inspect, the key (or path) of the value to retrieve, and the default value to return if the value cannot be found. The key can be a simple string for direct property access, or it could be a more complex structure, such as a dot-separated string (e.g., "user.address.street"), allowing for nested property retrieval.

When getValueobjOrDefault is called, it first attempts to access the value at the specified key within the provided object. If the object itself is null or undefined, or if the key does not exist, or if the value associated with the key is null or undefined, the function returns the provided default value. Otherwise, it returns the actual value found at the specified key.

This pattern is particularly useful in scenarios where data might be incomplete or where certain optional fields are expected. For example, when parsing JSON data from an API where some fields might be omitted, or when dealing with user-configurable settings that may not have all options defined. Using getValueobjOrDefault makes code more robust and readable by eliminating the need for multiple conditional checks.
