This javascript question is simple.

Let's see how much you know about strings and numbers.
#programming

In JavaScript, when you add numbers together, they add up. But if you mix in a string, it gets stuck to the end. So, 3 + 4 + '5' becomes '75'. Cool, right? 🤓 #JavaScript #Programming

CSS Object-fit Property🔥

You can set the resizing behaviour of an image or video to fit it in its container using the object-fit property.

The answer is 10 as 20 can not be accessible due to block scope which restricts the access from outside .

As a web developer today, most of your works are related to APIs.

But most of developers don't actually understand what it is. 👀

When we talk about API, we are usually referring to Web API. 🌐

Web API (Application Programmatic Interface) can provide:

1. Resources, e.g. bus arrival time, restaurant ratings...
2. Services or microservices, e.g. converting coordinates into place names, creating QR codes...

With Web APIs, developers can then easily incorporate these building blocks into other web applications.

👩‍💻There's some features of different Web API, for example:

1. Public vs. private
- Public APIs are available to everyone, but may subject to licenses
- Private APIs are only available to internal developers

2. Free vs. premium
- Premium APIs may charge on-demand
- That's why there's also this term “API Economy”!

There's actually API marketplace and directory site, like
- RapidAPI
- ProgrammableWeb

Here's some example of public API that you can explore:

1. Google (developers.google.com/apis-explorer)

2. Facebook (developers.facebook.com/docs/apis-and-…)

3. Data portals of many cities (dataportals.org/search)And you also have to understand what is 'API endpoints'.

API usually provides endpoints as a URI to provide services.

And it needs to be static, without affecting applications built upon ✨And that's why there's a standard for writing API called REST.

REST stands for 'REpresentational State Transfer'.

It's an architectural style of writing APIs.

JS devs: what's the output for this? 😀🛠️
