Function applyPatch

applyPatch<T>(
    document: T,
    patch: readonly Operation[],
    validateOperation?: boolean | Validator<T>,
    mutateDocument?: boolean,
    banPrototypeModifications?: boolean,
): PatchResult<T>
Apply a full JSON Patch array on a JSON document. Returns the {newDocument, result} of the patch. It modifies the document object and patch - it gets the values by reference. If you would like to avoid touching your values, clone them: jsonpatch.applyPatch(document, jsonpatch._deepClone(patch)).
