JSON data structure-tool
JScheme也可以处理常见的JavaScript对象
这是个用来解构和操作JSON对象这种嵌套结构的工具。
Path是一个中间件，用来打散嵌套结构的对象。Path的第2个参数(true|false)，会决定是否按内置对象PathItem来返回结果。
const { path } = require('./path');
let a = {
zz: null,
aa: 1,
bb: '222',
cc: [1, 2, 3, {
aaa: 1,
ccc: 3
}],
dd: 4,
ee: [1, {
aaa: 1,
ccc: [9, 8, 7]
}],
ff: [-1, -3, -5],
gg: 1
};
console.log(path(a, false));
// 输出
