A JavaScript utility library delivering consistency, modularity, performance, & extras.
@illuminist thank you for your "join". Unfortunately, I'd not seen your answer at the time. So we, with guys came up with different solutions) https://codesandbox.io/s/test-algorithms-environment-dmz8b check algoritms.js , yours the last but looks like the simplest and almost the most efficient one (watch console). )) The only one downside - it's the right-join, but it's ok)
@kokushkin I think I heard different criteria at that time. Btw, I had created a new one with correct requirement, improved performance, able to accept more than 2 arrays, and able to handle case of having same key in same array: https://codesandbox.io/s/test-algorithms-environment-54zhq
Actually didn't use lodash function because need to optimize for raw performance.
@illuminist thank you again. Good idea! So, it seemed like a generalization of the "joinByBogdan" but you'd used "Object.assign(hash[item.key], item)" instead of "hash[item.key] = { ...hash[item.key], ...item }; " . And It works much faster! Up to 10 times faster in this scenario! Cool.
Hello, I am putting my data into the state with cloneDeep as below. However, when the props change, the state does not change.
How should I proceed?
state = cloneDeep (this.props.modelData);
Or if you don't need to update state inside component, you can just render using data from this.props directly
Hello, please tell me what can be done in my case? (Angular)
I have a model with a lot of elements and every time I call cloneDeep, the processing time of the model (almost doubles) is increased, although the model does not change significantly.
In this case, there is a page component that contains a list of tabs. In each tab, a complex component is generated. When I click on the tab, ngOnInit is called with cloneDeep for the model based on which the component is rendered
The model contains reactive properties.
ctx.selectedPlayers.forEach((player) => {
const comparableMatches = player.matches.map((match) => ({
teamName: match.teamName,
matchId: match.matchId,
eloDiff: match.eloDiff,
map: match.map,
win: match.win,
time: new Date(match.time),
}));
allMatches.push(comparableMatches);
});
return _.intersectionWith(...allMatches, _.isEqual);
Its signature is
(object1, object2) => boolean
I think I got it working now :D
Thanks for the help :)
Or more like find a specific object and set a value on that object.
Hi. I'm interesting what community think about a this proposal: memoize: Warning: for memoized function with 2+ args use resolver lodash/lodash#4641 implemented here lodash/lodash#4702
If you like it, please send a reaction in issue or comment or suggest changes/help with implementation

Can you use some of lodashes functions to do the same?
can someone please explain to me what is happening here as I am a beginner ?
It isn't an usual syntax that you use in everyday job, but still good to know
hello, I am new in lodash so i don't know how to use with react native. I have a question. I have a project which is related to firebase. I want to see the information of which user logs in.With the map function, I can access all the data in the database but I only want to see the data of the logged-in user.should I use the find function to achieve this?Do you have a suggestion?
const mapStateToProps=state=>{
const currentUser=firebase.auth().currentUser;
const email=currentUser.email;
const profileInformationList=_.map(state.profileInformationList,(val,uid)=>{
return {...val,uid}
});
return {
profileInformationList
}
}
const currentUser=firebase.auth().currentUser;
const email=currentUser.email;
const profileInformationList=_.map(state.profileInformationList,(val,uid)=>{
return {...val,uid}
});
return {
profileInformationList
}
}
I want to use currentUser.email
