It was a beautiful idea — but it was better off as an idea than an actual product. The concept of The Point was so novel

ows, I could see the Waning Gibbous Moon still high in the crystal-clear sky. I grabbed my DSLR and shot a few photos of it from the vantage point of my window. My 200 mm lens lets me get quite close, but I also tried to get a shot that captured the window frame and put Earth’s satellite in context. The shots came out well and I shared them on Instagram.

To make it easier for computers to understand these new concepts, Python uses a programming pattern called object-oriented programming, which models concepts using classes and objects. This is a flexible, powerful paradigm where classes represent and define concepts, while objects are instances of classes. In the car example, we can create a class called car that defines its characteristics to the computer. We would be able to create thousands of instances of that class car, which are the individual objects of that class.

“A lot of the examples that got me most excited, like the idea of building a dome over the city of Chicago which is something that if you had a way to go to everyone in Chicago and say, what would it be worth to you to make the winters here obsolete, people would say like, I don’t know, $10,000. Everyone would. Before you know it, you would have billions and billions of dollars for this project.”

Since 2015, JavaScript has been receiving constant yearly updates with new features being added. Though ES2021/ES12 will be released next year, we can already have a look at what’s to come since many features already reached Stage 4(Finished) specification and will be included in the specification. In this article, I will discuss the features that have already reached stage four and are added to the Google Chrome V8 engine.

Promise.any() method takes in a list of promises and returns a value, as soon as it hits the first resolved promise from the list. If all the promises are rejected then it will throw an AggregatedError message.

When explaining to a computer what kind of object this is, it’s a good idea to approach it in a similar way. Computers have no innate idea of what a car is, why were they created or who uses them. And if you want your computer to correctly understand the object, a car in this case, you have to clearly explain which are its attributes.

The idea was that if enough people pledge to a cause, it would be much easier for that cause to gain traction. But it wasn’t exactly political activism Andrew was interested in.

In my previous article about strings, I explored a bunch of methods and attributes of the string class. Take a look at it for further insights about how to treat strings objects, which in that case will be a different instance of the string class. This means that they all have the same methods, although the content in the string is different.

You might want to start saying that it’s a wheeled motor vehicle used for transportation. Also, you might say that there are several brands of car-maker companies, which make different types of cars that fulfill various needs. In an even more basic level you might say that it has four tires, that they carry up to five people in most cases and that they are mainly used to transport people, not goods.

As you can see in the image above, when we use the type function as we just did here, Python tells us which class the value or variable belongs to. And since integers and strings are classes, they have a bunch of attributes and methods associated with them. You can access attributes and methods of a class with the dir function in Python, as shown below:

In the car example, color and brand are two attributes associated with every instance, or car, created with the program. On the other hand, methods would be actions performed with or by the car, such as driving. A more computer-oriented example would be a file in a directory, as every file has a name, a size and a date of when it was created.

The idea of object-oriented programming might sound abstract and complex, but if you’ve programmed any software you might have already used objects without even realizing it. Almost everything in Python is an object, all of the numbers, strings, lists, and dictionaries are included in this type of element. The core concept of object-oriented programming comes down to attributes and methods associated with a type:

String.prototype.replace is an existing method that allows us to replace a pattern in a string with something else. One thing to remember in this method is that, when we replace a pattern, only the first occurrence of that pattern in the string would be replaced. To replace all the occurrences, we use RegEx to achieve the same.
