'I am looking for a solution to group objects by a unique key together
I currently have an array something like this, there is a unique key in each object I can use (example: "_key": "qpfPdAZdFk"), I want to be able to group them into their own arrays
[
{
"node": {
"entity_as_json": {
"_key": "qpfPdAZdFk"
},
1:1
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdabcd",
},
2:2
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdAZdFk"
}
3:3
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdAZdFk"
},
4:4
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdabcd",
},
5:5
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdabcd",
},
6:6
},
]
I want to be able return a grouped together array's like this
[
[
{
"node": {
"entity_as_json": {
"_key": "qpfPdAZdFk"
},
1:1
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdAZdFk"
}
3:3
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdAZdFk"
},
4:4
},
],
[
{
"node": {
"entity_as_json": {
"_key": "qpfPdabcd",
},
2:2
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdabcd",
},
5:5
},
{
"node": {
"entity_as_json": {
"_key": "qpfPdabcd",
},
6:6
},
]
]
I have been trying to think of a solution but I cant seem to get it working, is there some kind of way in JavaScript to identify by unique? I can use Lodash if that would work.
Any help much appreciated
