本文介绍了ECMAScript 2017中新增的Object.entries()函数。该函数允许开发者遍历对象属性并将其作为键值对读取。示例展示了如何使用此函数获取对象的所有键值对。
The Object.entries() function is an addition to the ECMAscript scpec in Es2017. This allows us to iterate through the properties of an object and read the entries as keys and objects.
const obj = { foo: 'bar', baz: 42 };
console.log(Object.entries(obj)); // [ ['foo', 'bar'], ['baz', 42] ]
