Say I have an object:
"changes": {
"attr1" : [
"sub_attr1": false,
"sub_attr2": true,
...
],
"attr2" : [
"sub_attr1": false,
"sub_attr2": true,
...
],
...
}
I want to extract an specific attr of the changes object to a new one. Lets say I want to extract attr1.
"new_obj" : [
"sub_attr1": false,
"sub_attr2": true,
...
]
and
"changes": {
"attr2" : [
"sub_attr1": false,
"sub_attr2": true,
...
],
...
}
How may I achieve this?
Something like this will work.
const extract = (obj, keyToExtract) => {
const entries = Object.entries(obj);
const entry = entries.find(([key, value]) => key === keyToExtract);
if(entry) {
delete obj[keyToExtract]
return {
"new_obj": entry[1]
}
}
}
extract(obj.changes, "attr1")
Se changes é um objeto então você pode buscar os filhos dele assim changes.filho (objeto)
Sendo array: changes['filho'] (array)
