I want to have an input number that allows any float between 0-1 including both whole numbers. But it’s proving quite tricky just getting the backspace to actually delete a numbers as it comes as NaN
I got this:
const [rate, setRate] = useState<number>(0)
const addRate = (num: number) => {
if (typeof num !== 'number') {
setRate(0)
} else {
setRate(num)
}
}
...
<input
type='number'
value={rate}
onChange={e => addRate(parseFloat(e.target.value)}
/>
For over a week I have been trying to fix this error and I have not been able to figure it out how to fix it. I used react-native-voximplant to build P2P video calling following a tutorial, but I wanted to extend it with conference call/live broadcast like Zoom or MS Teams, but as soon as I installed react-native-webrtc I got the duplicate error. When I uninstall react-native-webrtc my app works fine. But I really want to use react-native-webrtc to achieve it not react-native-voximplant.
So how do I overcome this duplicate error? Thanks in advance for your kind help.
Here’s the screenshort of the error messages:
I want to trigger 2 functions with a unique timeOut.
The following works fine
setTimeout(function() {
function1(); // runs first
function2(); // runs second
}, 1000)
But in my case, I have a class method and an callback (arrow function).
It looks like this (minimalized):
class Timer {
constructor(callback) {
this.active = false;
this.callback = callback;
}
cancel() {
this.active = false;
}
set() {
this.active = true;
this.timeOut = setTimeout( function() {
this.cancel();
this.callback; // HERE is my problem. doesn't run, not casted as a function
}, 1000)
}
I get the following error Expected an assignment or function call and instead saw an expression.
Any trick to fix that?
I’m JavaScript beginner.
I got one Object from an API like
data= {
key1: “v1”
key2: “v2”
key3: “v3”
}
the above value is returned when I debug it like
console.log(data),
I wanna use v3 value, but when I tried to get it like below, “Undefined” came. expected result is “v3”
var v3 = data.key3;
am able to get v1 and v2 values, but v3 failed.
Also, if i debug it like
console.log(JSON.stringfy(data));
the returned value is
{key1: "v1"
key2: "v2"}
I am wondering why thiskind of missing key and value is occuring..
If you have any suggestions, please let me know it.
Thanks
Input: Given two non-empty linked lists representing two non-negative integers. The digits are stored in reverse order, and each of their nodes contains a single digit. Add the two numbers and return the sum as a linked list.

Good morning everyone!
I’m developing an application with Node.js and Angular, and I’m getting a little stuck lately.
I need to append a custom key -> value to an existing query result collection.
This is the function I have:
exports.findAll = (req, res) => {
Project.findAll({
include: [{
all: true,
include: [{
all: true
}]
}]
})
.then(data => {
data.forEach(
(project) => {
// <-------- HERE GOES THE APPEND
}
);
res.send(data);
})
.catch(err => {
res.status(500).send({
message: err.message || "Error retrieving projects"
});
});
};
Description:
After getting the result from the model query, I iterate over each result (aka Project).
Then, what I need to do is append a key -> value pair to that very Project.
By now, I’d like to do something like this:
exports.findAll = (req, res) => {
Project.findAll({
include: [{
all: true,
include: [{
all: true
}]
}]
})
.then(data => {
data.forEach(
(project) => {
project.cat = "miaw";
}
);
res.send(data);
})
.catch(err => {
res.status(500).send({
message: err.message || "Error retrieving projects"
});
});
};
This try hasn’t made any changes in my JSON collection, and I don’t know how to accomplish it neither.
Could someone give me some help?
I’ve searched everywhere but couldn’t find anything useful.
Thank you so much!
I am trying to generate JS code with the following tsconfig.json
{
"compilerOptions": {
/* Language and Environment */
"target": "es2016", /* Set the JavaScript language version for emitted JavaScript and include compatible library declarations. */
"lib": ["ES2019","dom"], /* Specify a set of bundled library declaration files that describe the target runtime environment. */
/* Modules */
"module": "esnext", /* Specify what module code is generated. */
"moduleResolution": "node", /* Specify how TypeScript looks up a file from a given module specifier. */
"baseUrl": "./", /* Specify the base directory to resolve non-relative module names. */
/* JavaScript Support */
"allowJs": true, /* Allow JavaScript files to be a part of your program. Use the `checkJS` option to get errors from these files. */
/* Emit */
"outDir": "./dist/", /* Specify an output folder for all emitted files. */
"noEmit": true, /* Disable emitting files from a compilation. */
/* Interop Constraints */
"isolatedModules": true, /* Ensure that each file can be safely transpiled without relying on other imports. */
"allowSyntheticDefaultImports": true, /* Allow 'import x from y' when a module doesn't have a default export. */
"esModuleInterop": true, /* Emit additional JavaScript to ease support for importing CommonJS modules. This enables `allowSyntheticDefaultImports` for type compatibility. */
"forceConsistentCasingInFileNames": true, /* Ensure that casing is correct in imports. */
/* Type Checking */
"strict": true, /* Enable all strict type-checking options. */
/* Completeness */
"skipLibCheck": true /* Skip type checking all .d.ts files. */
},
"include": ["src/**/*.ts", "src/Container.js"],
"exclude": ["node_modules/**/*", "dist/**/*","konva/*"],
}
This configuration generates one js file in the dist directory for each TS file, this way I can mantain the file structure.
The problem is that I need to import Konva lib from npm in order to use it, and when I compile I get this import in the JS files which need this lib:
import Konva from "konva"
This raises an error because it is not a valid path. Right now I have a python script removing this line from the resulting files, but I would like to remove it because it is an extra dependency just for removing one line.
When running the website it does not have any problem because I import Konva lib from CDN.
I am pretty new to TS and I don’t know if it is possible to remove the import statement from npm modules or if I have to bundle everything together, any tip is welcome.
Thanks.
I would like to make my bot so that it sends logs to a given channel that someone will set up beforehand, for example, will enter the command set log channel <channel> and then the bot will send logs there. So far, I have only managed to do the command for which the bot will send messages to a given channel, but only after entering the channel id. Thank you in advance for help.
I am starting aframe and I cant display some informations (a small text) on pictures.

I want to achieve the following using Formik and Fieldarray.
I want to render a new input field whenever the user starts writing in the current input field.
so I want to eliminate the button.
so instead of having a (+) button to add a new field:
I want to have it like this:
I tried to do it using variant.length > 1 but it’s not what I want because it will add a new field every time the length of variant is larger than one, and I want it only for the previous field array.
I wrote this code so far
const handleSubmit = async (e) => {
e.preventDefault();
let formValues = ref.current.values;
console.log('Form Data received', formValues);
let formData = new FormData();
formData.append('name', formValues.name);
for (let key in formValues.variants) {
formData.append(
'variants[key].variantName',
formValues.variants[key].variantName
);
}
await axios.post('http://localhost:4000/variants', formValues);
};
