由于一些你知道的原因gist在国内经常无法访问，我搬运下源码
/**
* Deep diff between two object, using lodash
* @param {Object} object Object compared
* @param {Object} base Object to compare with
* @return {Object} Return a new object who represent the diff
*/
function difference(object, base) {
function changes(object, base) {
return _.transform(object, function(result, value, key) {
if (!_.isEqual(value, base[key])) {
result[key] = (_.isObject(value) && _.isObject(base[key])) ? changes(value, base[key]) : value;
}
});
}
return changes(object, base);
}
ex:
var a = {name:89757,date:{year:2017}}
var b = {name:89757,date:{year:2017,month:3}}
difference(a,b)
//{date:{month:3}}
