我对打字稿很陌生.tsconfig.json 中的 Target 是什么意思?

I am quite new to Typescript. What does Target in tsconfig.json signify?

target 表示应该从给定的 TypeScript 发出哪个 JavaScript 目标.例子:

()=>null 会变成 function(){return null} 因为 ES5 没有箭头函数.

()=>null will become function(){return null} as ES5 doesn't have arrow functions.

()=>null 会变成 ()=>null 因为 ES6 有箭头函数.

()=>null will become ()=>null as ES6 has arrow functions.
