 // 比如 API 暴露 function useApi () { const a = 'a' const b = 'b' const c = 'c' return Object.assign([ a, b, c ], { a, b, c }) // 务必数组在前，否则无法维护下标 } // 使用时既可以 const [ a, b, c ] = useApi() // react hook 风格的数组解构

### Inconsolata

• Good: 一切都好，非常好看的等宽，第一眼很惊艳

### Monaco

• Good: 中规中矩，斜体好看
• Bad: 总感觉是被拉高了，感觉怪怪的，暂时发现小写 `m` 挤在一起不太好看

### Source Code Pro

• Good: 字体饱满，`i` `l` 特别，`0` 中间带点
