Because the default equality in ES6 uses the object references, we must create a custom data structure that handles the desired object equality rules as follows: classSetWithContentEquality<T>{privateitems:T[]=[];privategetKey:(item:T)=>string;constructor(getKey:(item:T)=>string){this.getKe...
TypeScript Set Set is a new data structure introduced in ES6. It allows to store distinct values into a List. Learn to create set, add and iterate set values. TypeScript Map Map is a new data structure introduced in ES6, to store key-value pairs. Learn to create map, add, delete, ...
总体上来说面向对象型的语言更多地采用 Nominal Type System,函数式语言偏向于采用 Structure Type System,JavaScript 是一种非常独特的语言,两种编程范式兼而有之,不过近些年来主流方向是函数式,arrow function、Promise 等语言特性遍地开花,React、RxJS、Ramda 等社区方案备受推崇。TypeScript 顺势而为,解决 JavaScript ...
一个典型等实例是 Iterable,它并不要求像 C++ 一样要求实例必须继承于某个父类或者像 Java 一样要求实例实现某个Interface,它只检查当前的对象是否实现了@@iterator方法。TypeScript 对症下药,接地气地采用了 Structure Type System 来为 JavaScript 量身定制一套灵活的类型系统。 下面这个例子比较能够说明这一类型系...

One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit tar...
