Converting numbers and strings to Boolean values can allow us to evaluate data within binary terms and can be leveraged for control flow in our programs. This tutorial covered how JavaScript handles conversion of its primitive data types. Though due to type coercion, data types will implicitly con...

2. Primitive TypesAccording to the ECMAScript specification, JavaScript has six primitive data types: string, number, bigint, boolean, undefined, and symbol. These types are immutable, meaning their values cannot be altered. There is also a special primitive type called null, which represents the...
一个Program是SourceFile的集合并带有一系列CompilerOptions。 通过调用createProgram API来创建Program。 通过一个Program实例创建TypeChecker。 TypeChecker是TypeScript类型系统的核心。 它负责计算出不同文件里的Symbols之间的关系,将Type赋值给Symbol,并生成任何语义Diagnostic(比如:error)。
