javascript / angular 如何把object转成array

取出的api 格式是纯object格式

{"name":"james","city":"Taipei","country":"Taiwan"}

用ngFor跑表格跑不出来 因为不支援object格式

要怎么把他变成array格式?

想变成

json array [ {"name":"james","city":"Taipei","country":"Taiwan"} ]
方法

let o = {"name":"james","city":"Taipei","country":"Taiwan"}
let arr = [o]
