Understanding Class Fields and Static Properties
Hello! Welcome to this article about Class Fields and Static Properties!
ES15 added the ability to define class fields and static properties directly within the class body. This eliminates the need for constructor functions to initialize properties, leading to cleaner and more concise code. This is about understanding this new feature!
1. Define a class.
You need to define a class to use it:
class myClass { }
2. Put the properties in the class.
Putting the properties in the class defines the properties:
class myClass { property1; property2; }
You can add as many properties as you need.
3. Add the constructor() function.
Add the constructor function to define the keys in the this object for the properties:
class myClass { property1; property2; constructor(property1, property2) { this.property1 = property1; this.property2 = property2; } }
4. Example
This is an example of using this new feature in JS:
class Person { name; age; constructor(name, age) { this.name = name; this.age = age; } }
5. Conclusion
And that is the conclusion for this post!

Once you have mastered the entry-level TypeScript tutorial, you should be able to write your own code in an IDE that supports TypeScript and compile it into JavaScript. This tutorial will dive into various data types in TypeScript. JavaScript has seven data types: Null, Undefined, Boolean, Number, String, Symbol (introduced by ES6) and Object.

This tutorial will explain how to create pie, ring, and bubble charts using Chart.js. Previously, we have learned four chart types of Chart.js: line chart and bar chart (tutorial 2), as well as radar chart and polar region chart (tutorial 3). Create pie and ring charts Pie charts and ring charts are ideal for showing the proportions of a whole that is divided into different parts. For example, a pie chart can be used to show the percentage of male lions, female lions and young lions in a safari, or the percentage of votes that different candidates receive in the election. Pie charts are only suitable for comparing single parameters or datasets. It should be noted that the pie chart cannot draw entities with zero value because the angle of the fan in the pie chart depends on the numerical size of the data point. This means any entity with zero proportion
