static {}initialization blocks are evaluated in document order interleaved with static field initializers. Astatic {}initialization block may not have decorators (instead you would decorate the class itself). When evaluated, astatic {}initialization block'sthisreceiver is the constructor object of the ...
总的来说,class static block 在 Class 内创建了一个块状作用域,这个作用域内拥有访问 Class 内部私有变量的特权,且这个块状作用域仅在引擎调用时初始化执行一次,是一个比较方便的语法。 原文下方有一些反对声音,说这是对 JS 的复杂化,也有诸如 JS 越来越像Java的声音,不过我更赞同作者的观点,也就是 Js 中 C...
The ECMAScript proposal “Class static initialization blocks” by Ron Buckton is at stage 4 and scheduled to be included in ECMAScript 2022. For setting up an instance of a class, we have two constructs in JavaScript: Field: Create (and optionally initia
class-static-block 提案于 2021.9.1 进入stage4,是一个基于 Class 增强的提案。 本周我们结合 ES2022 feature: class static initialization blocks 这篇文章一起讨论一下这个特性。 概述 为什么我们需要 class static block 这个语法呢?其中一个原因是对 Class 静态变量的灵活赋值需求。以下面为例,我们想在 Class...
You can combine multiple class field initializers and class initialization blocks in an application. Listing 6 provides an example. Listing 6. Performing class initialization in top-down order class MCFICIB { static int x = 10; static double temp = 98.6; static { System.out.println("x = " ...
