arr = [
{id:1,name:""},
{id:2,name:"", children:[
{id:4,name:""}
]},
{id:3,name:""}
];
how do you reorder the array above into the following format?
newArr = [
{id:1,name:""},
{id:2,name:""},
{id:4,name:""}
{id:3,name:""}
];
guys, help me take a look. Thank you
function trans (arr) {
return [].concat.apply([], arr.map(cur => {
return [{id: cur.id, name: cur.name}].concat(cur.children ? trans(cur.children) : [])
}))
}
let newArr = trans(arr)let arr = [
{id:1,name:''},
{id:2,name:'', children:[
{id:4,name:''}
]},
{id:3,name:''}
];
function format(arr) {
return arr.reduce((result, item) => {
return [...result, {id:item.id,name:item.name}, ...item.children || []]
},[]);
}
console.log(format(arr));
