So I have a string below
'user.name.firstName=Anatoliy&user.name.lastName=Klimov&user.vip=true'
I’ve to parse it to Object looks like
{
"user": {
"name": {
"firstname": "",
"lastname": ""
{
"vip": true
}
}
>Solution :
Here’s an approach
const data = 'user.name.firstName=Anatoliy&user.name.lastName=Klimov&user.vip=true';
const constructObject = (str) => {
const paths = str.split('&');
const result = {};
paths.forEach((path) => {
const [keyStr, value] = path.split('=');
const keys = keyStr.split('.');
let current = result;
for (let i = 0; i < keys.length - 1; i++) {
if (!current[keys[i]]) {
current[keys[i]] = {};
}
current = current[keys[i]];
}
current[keys.pop()] = value;
});
return result;
};
console.log(constructObject(data));
