mergeDeep

The mergeDeep function is a utility method provided by the web3.utils module that performs a deep merge of two or more objects. The function takes a single required parameter, destination, which is the object that will receive the merged properties, and an optional parameter, sources, which is an array of objects that will be merged into the destination object.

The mergeDeep function performs a recursive merge of the destination and sources objects, deeply merging the properties of each object into the destination object. This means that if any of the sources objects contain properties that are also present in the destination object, those properties will be overwritten with the values from the sources objects.

The function returns a new object that contains all the properties from destination, source1, and source2. The resulting object has properties name, age, address, street, city, state, and zip, with the values from source1 and source2 overwriting the corresponding values in destination.

The mergeDeep function is useful for combining data from multiple sources into a single object, or for overriding properties in an object with values from another object. It can be used in a variety of contexts, such as when working with JSON data, constructing objects from database queries, or merging configuration files.
