javascript - 我怎样才能导出一个const，它是变量的值

Question

如果可以的话，显示代码更容易解​​释我正在寻找的内容。

validations.js 文件

export const required = 'REQUIRED'
export const email = 'NEEDS_TO_BE_EMAIL'

translations.js 文件

import { required as requiredValidation, email as emailValidation } from './validations'

export const { [requiredValidation], [emailValidation] } = defineMessages({
    [requiredValidation]: {
        id: `validations.${requiredValidation}`,
        description: 'Mensagem de obrigatoriedade do campo',
       defaultMessage: '{field} é obrigatório'
    },
    [emailValidation]: {
        id: `validations.${emailValidation}`,
        description: 'Mensagem de formato de email do campo',
        defaultMessage: '{field} precisa ser do tipo e-mail'
    }
})

我想导出常量:

REQUIRED 和 NEEDS_TO_BE_EMAIL，有办法做到这一点吗？

感谢您的进步!

据我所知这是不可能的。但这是你可以做的。不过，您可以使用动态生成的键导出单个对象:

let obj = {};

obj[fooLabel] = fooValue;

export default obj;
