问题描述
我的问题与...不同:
- TypeScript真的是JavaScript的超集吗?
ES6 不是(或者没有被考虑过,如果你在未来看到这个)当前版本的JavaScript - Typescript!= ES6?
这是不同的,我知道,而不是我在问。
解决方案
根据当前语言规范可在网站上获得:
TypeScript是JavaScript的语法糖。 TypeScript语法是Ecmascript 5(ES5)语法的超集。
And:
TypeScript语法包括几个提出的Ecmascript 6(ES6)功能,包括类和模块。
In other words, is all ES6 syntax covered by TypeScript?
How is my question differente from:
- "Is TypeScript really a superset of JavaScript?"
ES6 isn't (or hasn't been considered if you read this in the futur) the current version of Javascript - Is Typescript != ES6?
It's different, I know that, not what I'm asking.
解决方案
Based on the current language specification available at the website:
TypeScript is a syntactic sugar for JavaScript. TypeScript syntax is a superset of Ecmascript 5 (ES5) syntax.
And:
TypeScript syntax includes several proposed features of Ecmascript 6 (ES6), including classes and modules.
