I tried to use fs.writeFileSync () / fs.wirteFile even though I use think functions in AJAX browser and scream that fs.writeFileSync () / fs.wirteFile is not a function, maybe it only works for node js. I need to save AJAX data in a new file called tmpI.json. Does anyone have a role or something that helps me?
Thanks for your help.

Hey hai i am new to bootstrap 4 so i have this question. I downloaded a Bootstrap 4 web template that contained some Javascript Libraries like (lib / bootstrap / js / bootstrap.bundle.min.js) (lib / easing / easing.min.js) (lib / superfish / superfish.min.js)
(lib / venobox / venobox.min.js) (lib / owlcarousel / owl.carousel.min.js). It also has the same libraries in CSS also (lib / owlcarousel / assets / owl.carousel.min.css) (lib / venobox / venobox.css). Why there are two libraries in two different languagesjs and CSS,
And I went through the code and some classes were declared with it I would and were called CSS With #, And declare a class in I would means only in Javascript However, there is no JavaScript code that I downloaded in this web template.
I created a class with a method asyncHowever, when I instantiate this class and run the method, an error is generated in my console. Follow the sample code and error below:
JS
class MyClass{
async method(){
const x = await 10; // exemplo meramente ilustrativo
return x
}
}
const instance = new MyClass()
const result = await instance.method()
console.log(result)
Error:
const result = await instance.method()
^^^^^
SyntaxError: await is only valid in async function
Does async / await work differently when it comes to methods of an object? Or am I doing something wrong?
I try that when the user clicks on the text of the description (not in the title, in the content (@ Html.DisplayNameFor (model => model.Descricao)), a window (modal? Container?) Is opened that is complete Displays description.
I created this window like this:
Descrição
@Html.DisplayNameFor(model => model.Descricao)
How do I open the window when the user clicks on the description?
I would like to render this data in a table in HTML, where the "type" (beer, portions, etc.) should be the table header and the elements corresponding to the rows.
I want to build applications using React Native. I have already installed the necessary programs to start them. However, when I issue the cmd "npx react-native run-android" command, it loads for a long time and does not give me a message on the Android screen (& # 39; Welcome to React Native & # 39;), I don't know whether there has to be a mistake or something. I have already researched but found nothing.
Below I placed the photo of my screen that is only on it and does not change anything.
I wrote a function that checks the ratio of the number of positive, negative, and zero values within an array to length.
The code I wrote is the following:
function plusMinus(arr) {
/**first I declare 3 variables to store the positive, negative and null elements inside them*/
let numPositive = ();
let numNegative = ();
let numZero = ();
/**then I write a loop that will check whether
the elements of the input array are positive, negative or null,
e.g. if the element(i) is positive, then the array
numPositive pushes the positive element(i) inside it,
and so on for the rest of the numbers and arrays*/
for (let i=0; i0){
numPositive.push(arr(i)>0);
}else if (arr(i)<0){
numNegative.push(arr(i)<0);
}else{
numZero.push(arr(i)==0)
}
}
/**finally, the ratios are given as a result of
the length of the pushed arrays and the length of the original array*/
console.log(numPositive.length/arr.length);
console.log(numNegative.length/arr.length);
console.log(numZero.length/arr.length);
}
I would like to receive feedback on why my code's logic is not working.
