In this article, I’ll walk you through the various methods tocompare strings in TypeScript, from basic equality checks to more advanced techniques for sorting and case-sensitive comparisons. I’ve learned these approaches through years of development experience, and I’m excited to share them wi...
TypeScript 代码最终都会被编译成 JavaScript 代码来运行。这个编译的过程需要使用 TypeScript 编译器,我们可以为该编译器配置一些编译选项。 在TypeScript 项目的根目录下执行 “tsc-init” 命令,快速创建一个 tsconfig.json 文件。该文件用于配置 TypeScript 编译项目时编译器所需的选项。下面是该配置文件中比较常见的...
When we compare two classes, it compares members of instances only. The class constructor and static members belong to the class itself, so those are not included in the comparison.ExampleIn this code, we have the same instance members in variable 'a' and variable 'b'. So, when we ...
In TypeScript (or JavaScript), we can compare the two variables with either equality operator (‘==’) or strict equality operator (‘===’). Both comparison operators seems almost similar; but the way, they compare two given variables, is very different. The equality operator compares only...
To identify two Value Objects from each other, we look at the actual contents of the objects and compare based on that. For example, there might be a Name property on the User Entity. How can we tell if two Names are the same? It's pretty much like comparing two strings, right? "...
Compare<N, M>: Compares two number types N and M and returns a number indicating their relative order. GreaterThan<N, M>: Checks if the number type N is greater than M. GreaterThanOrEqual<N, M>: Checks if the number type N is greater than or equal to M. LessThan<N, M>: Check...
Description : There is currently no Chinese translation of the latest official documents of TypeScript on the Internet, so there is such a translat...

Generics allow us to write code that is abstract over actual types. For example,Record<K,V>is a generic type. When we use it, we have to pick two actual types: one for the keys (K) and one for the values (V). Generics are extremely useful in modern programming, as they enable us...
