kandi X-RAY | object.assign Summary
An Object.assign shim. Invoke its "shim" method to shim Object.assign if it is unavailable. This package implements the es-shim API interface. It works in an ES3-supported environment and complies with the spec. In an ES6 environment, it will also work properly with Symbols. Takes a minimum of 2 arguments: target and source. Takes a variable sized list of source arguments - at least 1, as many as you want. Throws a TypeError if the target argument is null or undefined.

QUESTION
Is it possible to two reduce objects into one by summing their properties like so for any generic object

QUESTION
Sometimes I find myself needing to initialize an object with a property that matches the property of another object. When the property name is the same, I want to be able to use shorthand syntax.
(For the purposes of the examples in this question, I'll just keep the additional properties to a tag: 1 property, and I'll reuse message in subsequent examples as the input/source of the information. I also indicate an extra unwanted property of message because I'm cherry-picking properties and do not intend to just use Object.assign to assign all the properties of message to the result.)
ANSWER
Answered 2021-Jun-15 at 16:26The best I have so far is
{ person: message.person, tag: 1 }.Is there shorthand initializer syntax to achieve this?
No, this is still they way to go.
hoping that a property name would magically be inferred from
person

...ANSWER
Answered 2021-Jun-15 at 18:27This was difficult for me to understand, so I wanted to share if anyone else has the same issue.
It seems that an async method will break a method chain, there's no way around that. And since fetch is asynchronous, await must be used, and in order for await to be used, the calling method must be declared async. Thus the method chain will be broken.
The way the method chain is called must be changed.
In my OP, I linked https://jsfiddle.net/47sfj3Lv/3/ as a much simpler version of the same problem. StackOverflow's 'fiddle' effectively blocks 'fetch' for security reasons, so I need to use JSFiddle for demonstration.
Here's a working version of the same code using then and how/why it works, and a slightly shorter version, because await can be specified with the the fetch, obviously.

So, I am working on an MVVM-based core SDK for use any time I am developing some Google Apps Script based software, called OpenSourceSDK. It contain core business logic, including base classes to extend. For example, the file Models/BaseModel.gs in it is defined to be:
ANSWER
Answered 2021-Jun-13 at 22:53I was able to get it resolved, but the solution is...hacky.
So, apparently, Google Apps Script exports only what is in globalThis of a project: just the functions and variables. No classes, no constants, ...
Probably has a lot to do with how ES6 works, with its globalThis behavior. One can see that in action, by creating a dummy function, a dummy variable, and a dummy class in their local developer console:
QUESTION
here is the code im using to listen to changes in my firestore database:
...ANSWER
Answered 2021-Jun-14 at 04:37You have two options here:
The simplest one is to clear the array every time your callback gets invoked, because
doc.docscontains all relevant data to rebuild the UI anyway. So this would be callingorders = []at the top of the callback.If you want more granular control over updating the UI, you can iterate over
doc.docChanges, which allows you to view the changes between the snapshots. So with this you can determine what documents were added to the snapshot (initially that'll be all of them), which ones were removed, and which docs were updated.
Many UI frameworks these days perform minimal updates to the UI based on the data you provide them with, so I'd definitely recommend checking whether that is the case for Vue too before taking the second approach.

...ANSWER
Answered 2021-Jun-12 at 02:01It looks like you're using the LabIcon component, yeah? https://github.com/jupyterlab/jupyterlab/blob/master/packages/ui-components/src/icon/labicon.tsx#L454
That's a class component, but useEffect and useState hooks can only be used in function components and in other hooks: https://reactjs.org/warnings/invalid-hook-call-warning.html
You can only call Hooks while React is rendering a function component:
Call them at the top level in the body of a function component.
Call them at the top level in the body of a custom Hook.

QUESTION
Working Stackblitz:
I implemented 2 calendars in html, for filtering the data between 2 dates. When i filter data for the first time, i will select both calendar dates and the data is filtering. Now we have both the inputs for calendar given right. Now my issue lies here. When i change the first calendar date. the second calendar remains the same with previously assigned date as we filtered previously. and there is no change in the filtering of data until we give inputs to both calendars again. I want the second calendar value to be cleared on changing the first calendar. And also clear the first calendar input when the second calendar is changed. Please help me achieve this.
can we trigger the output based on either of the input values ? as of now it's not showing. example: i have 2 records in grid: with dates : 07/12/2020 and 15/12/2020 Initially if i filter from dec 1st 2020 to dec 31st 2020. It's showing both records. Now, again if i set 15/12/2020 in first calendar without changing second. There is no change in the table. i should enter second also. Can we fix it ??
...ANSWER
Answered 2021-Jan-04 at 12:04You are not updating the list on the change of the first Date input. Update the list onChange of the first Date if the second Date already been selected. Change your code as below.
