详解ES6 中的Object.assign()的用法实例代码

var object1 = { a: { b: 1 } };

ar object2 = Object.assign({}, object1);

object1.a.b = 2;

console.log(object2.a.b);

function copyFnc(origin) {

return Object.assign({}, origin)}

var sur = { a: 1, b: 2 };

console.log(copyFnc(sur));

function clone(origin) {

let originProto = Object.getPrototypeOf(origin);

return Object.assign(Object.create(originProto), origin);

}

const merge = (target, ...sources) => Object.assign(target, ...sources);

const merge = (...sources) => Object.assign({}, ...sources);

const DEFAULTS = {
logLevel: 0,
outputFormat: 'html'};
function processContent(options) {let options = Object.assign({}, DEFAULTS, options);
}
