set

Set a value at a given path.

This method chains a set operation to the patch.

The operation creates a new value at the specified path, overwriting any existing value.

Atomicity

If the parent path does not exist, or is not a collection, the operation fails and the entire patch is discarded.

Signature

This method has the following signature:

patch.set(path: string, value: JsonValue): Patch

The return is the Patch instance itself to allow operation chaining.

Here is a basic example of how to use this method:

path.set('address.city', 'New York');

The following list describes the supported parameters:

path string: The path to the value to set in dot notation, like address.city.
value JSON: The value to set at the specified path, like New York.
