QUESTION
I upgraded to React 18 and things compiled fine. Today it seems every single component that uses children is throwing an error. Property 'children' does not exist on type 'IPageProps'.
Before children props were automatically included in the FC
interface. Now it seems I have to manually add children: ReactNode
. What is the correct typescript type for react children?
Is this part of the React 18 update, or is something screwed up in my env?
package.json
...ANSWER
Answered 2022-Apr-07 at 20:34It looks like the children
attribute on the typescript typings were removed.
I had to manually add children to my props; There is probably a better solution to fix this, but in the interim, this works.
QUESTION
I have a simple component see below, that basically attempts to grab some data from the formik FormContext using the useFormikContext hook.
However when attempting to write unit tests for this component it wants me to mock the hook which is fine, however, mocking the hook with typescript means returning well over 20 properties most of which are a variety of methods and functions.
Has anyone found a better way of doing this? Just seems a bit annoying even if I get it to work as I only need 1 field from the hook.

...ANSWER
Answered 2021-Dec-22 at 13:29I resolved this issue not 100% sure it is the best solution but have posted here in case it helps anyone with a similar issue.
I basically overwrote the FormikType allowing me to ignore all of the fields and methods I wasn't using, it clearly has some drawbacks as it is removing the type-safety, but I figured since it was only inside the unit test it is somewhat okay.

QUESTION
Having a navigation type definition as bellow, when I navigate from e.g AOne
to BTwo
with id:99
the console log of props.route.params
shows correct info. But props.route.params.id
throws type error
...TypeError: undefined is not an object (evaluating 'props.route.params.id')
ANSWER
Answered 2022-Mar-10 at 21:14The problem is with Props
which is a CompositeScreenProp
and that is for the following use case:
when you nest navigators, the navigation prop of the screen is a combination of multiple navigation props. For example, if we have a tab inside a stack, the navigation prop will have both jumpTo (from the tab navigator) and push (from the stack navigator). To make it easier to combine types from multiple navigators, you can use the CompositeScreenProps type
It is explicitly used for typing the navigation
prop. That is why the typing (including autocompletion) works for navigate
. We can check how this works step by step. The navigate
function receives the screen to which it should navigate.
This is typed using the CompositeScreenProp
! By specifying the screen
in the params
prop, it can extract the type of the props
from the CompositeScreenProps
. We can test this as well by not specifying the screen
.
Clearly, the Typescript compiler can not extract the type information here.
Hence, using the construction React.FC
does not extract the type information for the BTwo
props. This is a react-native construction. It has nothing to do with react-native-navigation.
It is specified in the react-native-navigation documentation on how to type the props of a screen in the Type checking screens section and this does not differ from typing a normal Javascript function using Typescript. A react-native functional component is, loosely speaking, a JS function that returns a JSX component. It is typed the usual way.

QUESTION
While debugging a problem in a numerical library, I was able to pinpoint the first place where the numbers started to become incorrect. However, the C++ code itself seemed correct. So I looked at the assembly produced by Visual Studio's C++ compiler and started suspecting a compiler bug.
CodeI was able to reproduce the behavior in a strongly simplified, isolated version of the code:
sourceB.cpp:
...ANSWER
Answered 2022-Feb-18 at 23:52Even though nobody posted an answer, from the comment section I could conclude that:
- Nobody found any undefined behavior in the bug repro code.
- At least some of you were able to reproduce the undesired behavior.
So I filed a bug report against Visual Studio 2019.
The Microsoft team confirmed the problem.
However, unfortunately it seems like Visual Studio 2019 will not receive a bug fix because Visual Studio 2022 seemingly does not have the bug. Apparently, the most recent version not having that particular bug is good enough for Microsoft's quality standards.
I find this disappointing because I think that the correctness of a compiler is essential and Visual Studio 2022 has just been released with new features and therefore probably contains new bugs. So there is no real "stable version" (one is cutting edge, the other one doesn't get bug fixes). But I guess we have to live with that or choose a different, more stable compiler.

I'm trying to create a sound using Fourier coefficients.
First of all please let me show how I got Fourier coefficients.
(1) I took a snapshot of a waveform from a microphone sound.
- Getting microphone: getUserMedia()
- Getting microphone sound: MediaStreamAudioSourceNode
- Getting waveform data: AnalyserNode.getByteTimeDomainData()
The data looks like the below: (I stringified Uint8Array, which is the return value of getByteTimeDomainData()
, and added length
property in order to change this object to Array later)
ANSWER
Answered 2022-Feb-04 at 23:39In golang I have taken an array ARR1 which represents a time series ( could be audio or in my case an image ) where each element of this time domain array is a floating point value which represents the height of the raw audio curve as it wobbles ... I then fed this floating point array into a FFT call which returned a new array ARR2 by definition in the frequency domain where each element of this array is a single complex number where both the real and the imaginary parts are floating points ... when I then fed this array into an inverse FFT call ( IFFT ) it gave back a floating point array ARR3 in the time domain ... to a first approximation ARR3 matched ARR1 ... needless to say if I then took ARR3 and fed it into a FFT call its output ARR4 would match ARR2 ... essentially you have this time_domain_array --> FFT call -> frequency_domain_array --> InverseFFT call -> time_domain_array ... rinse N repeat
I know Web Audio API has a FFT call ... do not know whether it has an IFFT api call however if no IFFT ( inverse FFT ) you can write your own such function here is how ... iterate across ARR2 and for each element calculate the magnitude of this frequency ( each element of ARR2 represents one frequency and in the literature you will see ARR2 referred to as the frequency bins which simply means each element of the array holds one complex number and as you iterate across the array each successive element represents a distinct frequency starting from element 0 to store frequency 0 and each subsequent array element will represent a frequency defined by adding incr_freq
to the frequency of the prior array element )
Each index of ARR2 represents a frequency where element 0 is the DC bias which is the zero offset bias of your input ARR1 curve if its centered about the zero crossing point this value is zero normally element 0 can be ignored ... the difference in frequency between each element of ARR2 is a constant frequency increment which can be calculated using

Hello I am trying to transfer a custom SPL token with the solana-wallet adapter. However i am having trouble getting the wallet's secret key/signing the transaction.
I've looked at these answers for writing the transfer code but i need to get the Singer and i have trouble figuring out how with solana-wallet adapter. These examples hardcode the secret key and since i'm using a wallet extension this is not possible.
How can you transfer SOL using the web3.js sdk for Solana?
How to transfer custom token by '@solana/web3.js'
according to this issue on the webadapter repo https://github.com/solana-labs/wallet-adapter/issues/120 you need to:
- Create a @solana/web3.js Transaction object and add instructions to it
- Sign the transaction with the wallet
- Send the transaction over a Connection
But i am having difficulty finding examples or documentation as to how to do step 1 and 2.
...ANSWER
Answered 2021-Dec-06 at 13:51So i found a way to do this, it requires some cleanup and error handling but allows for a custom token transaction via @solana/wallet-adapter
