for example, get a variable a , and this variable a may be an object returned by the server.
a: {
name: "xiaobe",
age: 22,
title: "xxx"
} I want to assign name and age of a to b (actually want to take out more attributes)
is there any quick and easy way? Now I think of deconstructing it like this:
const { name, age } = a;
b = { name, age }Why not?
const b = {name:a.name,age:a.age} const a = {name,age} = {name: 10, age: 20}
console.log (a) / / = > {name: 10, age: 20}
console.log (name) / / = > 10
console.log (age) / / = > 20
but name and age are global
b = {. Bpm. A}
