If you're coming from another language that does not have the "elseif" construct (e.g. C++), it's important to recognise that "else if" is a nested language construct and "elseif" is a linear language construct; they may be compared in performance to a recursive loop as opposed to ...

If your HTTP request contains "nested" parameters, you may specify them in your validation rules using "dot" syntax:1$this->validate($request, [ 2 'title' => 'required|unique:posts|max:255', 3 'author.name' => 'required', 4 'author.description' => 'required', 5]);...

In this example, if the unique rule on the title attribute fails, the max rule will not be checked. Rules will be validated in the order they are assigned.A Note On Nested AttributesIf the incoming HTTP request contains "nested" field data, you may specify these fields in your validation...

The break command is even more powerful than you might think because if you have code nested more than one layer deep that you need to break out of, you can follow the break command with a number to indicate how many levels to break out of, like this: break 2; The continue Statement...
The other point is that, and while this is only an opinion, it can be quite tiresome writing a bunch of nested callbacks and some argue that it makes the code significantly harder to follow. It’s not uncommon to see callbacks nested four, five, or even more levels deep inside Node cod...
