I am trying to create a new array. I have list of plugins with different versions, and I need to find plugins with same uniqueIdentifier but different versions, and create one array out of it. Example:
{
"uniqueIdentifier": "theme_test",
"version": "2011120800"
},
{
"uniqueIdentifier": "theme_test",
"version": "3011120800"
},
{
"uniqueIdentifier": "theme_test",
"version": "4011120800"
},
to be like this:
{
"uniqueIdentifier": "theme_test",
"version": [
"2011120800",
"3011120800",
"4011120800"
]
}
So, in my code I am getting all the information, but I cannot make it work to store this versions as an array. So I am checking the uniqueIdentifier and then the version, and trying to generate new array:
item.pluginVersions.items.forEach(function(plugin) {
pluginVersionsSupported.forEach(function(supportedPlugin) {
if (plugin.uniqueIdentifier === supportedPlugin.uniqueIdentifier) {
if (plugin.version == supportedPlugin.version) {
pluginData = {
uniqueIdentifier: plugin.uniqueIdentifier,
version: []// need to update this to be an array
}
}
}
})
I appreciate all the help.
you need to use Array.reduce method:
const data =
[ { uniqueIdentifier: 'theme_test', version: '2011120800' }
, { uniqueIdentifier: 'theme_test', version: '3011120800' }
, { uniqueIdentifier: 'theme_test', version: '4011120800' }
]
const result = Object.values(data.reduce( (r,{uniqueIdentifier,version}) =>
{
r[uniqueIdentifier] ??= { uniqueIdentifier, version:[] }
r[uniqueIdentifier].version.push(version)
return r
},{}))
console.log(result)Assuming you only have one pluginData: move the new object out of the loop so that it doesn't get created repeatedly, and in the loop push the version to the existing array.
pluginData = {
uniqueIdentifier: plugin.uniqueIdentifier,
version: []
}
item.pluginVersions.items.forEach(function(plugin) {
...
if (plugin.version == supportedPlugin.version) {
pluginData.version.push(plugin.version);
You may also use Array#reduce() and Object.entries() as follows:
const data = [{"uniqueIdentifier": "theme_test","version": "2011120800"},{"uniqueIdentifier": "theme_test","version": "3011120800"},{"uniqueIdentifier": "theme_test","version": "4011120800"}];
const groupedData = Object.entries(
data.reduce(
(prev, {uniqueIdentifier,version}) =>
({ ...prev, [uniqueIdentifier]:(prev[uniqueIdentifier] || []).concat(version) }), {}
)
)
.map(([uniqueIdentifier,version]) => ({uniqueIdentifier,version}));
console.log( groupedData );
