javascript - 我如何在此模板字符串中创建条件？

Question

现在我有这个对象:

const messages = {
  required: field => `${field} needs to be filled!`,
}

打印我:

nome needs to be filled

我试图在此模板字符串中创建一个条件，以根据条件更改字段的值。我尝试过类似的事情:

const messages = {
  required: field => `
   ${field => {
    if(field === 'nome') {
     'name'
    }
    if(field === 'endereco') {
     'address'
    }
   }} needs to be filled!
  `,
}

但是当我打印我收到的消息时:

field => { if(field === 'nome') { return 'name' } } needs to be filled!

我需要:

name needs to be filled

你把事情搞得太复杂了

const field = "nome";
const messages = {
  required: `${field === 'nome'?'name': field} needs to be filled!`
}
console.log(messages.required)

const messages1 = {
  required: field => `${field === 'nome' ? 'name' : field} needs to be filled!`
}
console.log(messages1.required("nome"))
