首先先安裝lodash

安裝方法

sudo npm install lodash

[sudo] password for sh: 
npm WARN saveError ENOENT: no such file or directory, open '/home/sh/test/node/01/package.json'
npm WARN enoent ENOENT: no such file or directory, open '/home/sh/test/node/01/package.json'
npm WARN 01 No description
npm WARN 01 No repository field.
npm WARN 01 No README data
npm WARN 01 No license field.

這樣就裝好了

然後寫下面這段程式碼

const _ = require('lodash');

var rows = {};
rows = [{"id":405,"client_id":62,"email":"sh@gmail.com","client":{"client_id":"dev"}},{"id":406,"client_id":26,"email":"sh@gmail.com","client":{"client_id":"skill"}},{"id":407,"client_id":62,"email":"sh@gmail.com","client":{"client_id":"test"}}];

let ids = [];
_.forEach(rows, (obj) => {
  ids.push(obj.client.client_id);
});

console.log(ids);

最後的結果

[ 'dev', 'skill', 'test' ]
