在immutableJS中,我试图将输出传递给。
名称:“此字段为必填。另一个错误。”, 年龄:“仅允许使用数字字符。”
const Immutable = require("immutable");
let error = Immutable.fromJS({
name: ["This field is required", "Another error"],
age: ["Only numeric characters are allowed"]
});

ONELINER :就地(this version of question的答案-示例)
Object.entries(error).map( x=> error[x[0]] = x[1].join('. ')+'.' );
let error = {
name: ["This field is required", "Another error"],
age: ["Only numeric characters are allowed"]
};
Object.entries(error).map(x=>error[x[0]]=x[1].join('. ')+'.');
console.log(error);
通过这种方式,您可以将其包装在函数中(不可变):
let var func = (e,r={})=>(Object.entries(e).map(x=>r[x[0]]=x[1].join('. ')+'.'),r);
let result = func(error) // run it in this way

您可以使用Array.reduce()
error.reduce((prev,next,key) => prev.concat(`${key}: "${next.join('. ')}". `),'')
