Author: GPT-4o

In Laravel, Service Pattern and Repository Pattern are two common design patterns used to structure the business logic and data layer. Each pattern has its purpose and responsibilities, and they can even complement each other.

1. Service Pattern

The Service Pattern is used to encapsulate business logic, making it reusable and independent of the controller or other layers. This is where you place the "what needs to be done" logic, such as calculations, complex workflows, or coordination of multiple repositories or APIs.

Key Characteristics:

• Focuses on business logic.
• Keeps controllers thin by moving complex logic out.

Debounce

Author: GPT-4o

Lodash's debounce function is used to limit how often a function is executed over time, even if it's called frequently. It's particularly helpful when you want to avoid unnecessarily calling a function multiple times in quick succession. This is especially useful for improving performance and user experience.

Example Scenario: Searching While Typing

Imagine you have a search bar where users type a query, and for each keystroke, a search request is sent to a server. If a user types "hello," five separate requests would be sent: one for "h," another for "he," then "hel," "hell," and "hello." This can overload the server and create lag.

Think of it like this:

Imagine building a Lego car. You have all the different bricks and pieces put together to form the car. Serialization is like taking that Lego car apart and putting all the bricks into a box. You can then ship that box to someone else, and they can use the instructions (the serialization format) to rebuild the exact same car from the bricks.

Common uses of serialization

Saving objects to files: You can serialize objects and save them to files on your hard drive, allowing you to load them back into your program later. Sending objects over a network: Serialization is essential for sending objects between different computers or applications, such as in web services or distributed systems.

nextTick

Author: Gemini

Vue.js uses a reactivity system to efficiently update the DOM when your component's data changes. However, these DOM updates aren't immediate; they happen asynchronously to optimize performance. This means there's a tiny delay between when you change data and when the browser reflects that change.

Why nextTick?

nextTick lets you run code after Vue has finished updating the DOM in response to data changes. This is crucial when you need to:

Null Coalescing (??) vs Ternary (?:) operators

• Null coalescing - check for null and performs next (?? ??=)
• Ternary - check for false and performs next (?:)

Testing

Functional and Unit testing

• Functional tests only in and out. Your soft becomes black-box, it kind of user behavior simulation
