i want to find biggests changerate in the prices in my coins data
like if SDT oldprice is 1.00 and
new price is 1.02 = 2%
and if it was the biggests changerate in the coins my script should printing it
but the script dont working
it only keep give me same coin
const math = require('mathjs');
const fetch = require('node-fetch');
get()
async function get() {
const response = await fetch("https://trade.kucoin.com/_api/currency/prices?base=USD&targets=&lang=en_US");
const coin1 = await response.json();
const olddata = coin1.data
const tokens = Object.keys(olddata)
const oldprice = Object.values(olddata)
get1()
async function get1() {
const response = await fetch("https://trade.kucoin.com/_api/currency/prices?base=USD&targets=&lang=en_US");
const coin2 = await response.json();
const newdata = coin2.data
const tokens = Object.keys(newdata)
const newprice = Object.values(newdata)
function findLargestDifference() {
var large = null;
var index = 0;
for (var i = 0; i < oldprice.length; i++) {
var change = tokens[i].newprice / oldprice[i].oldprice;
if (change > large) {
large = change;
index = i;
}
}
console.log(tokens[index])
return tokens[index];
}
findLargestDifference()
}
}
here how data looks https://prnt.sc/19syjjg
I'm trying to update the data in nested map fields in firestore, my form is a window form that has 4 sides (wSide1,wSide2,wSide3,wSide4), what my form is doing is if customer select 1 field which is wSide1 and it needs to be updated then only this field only be updated but in my case it is updating all 4 sides, the one which is selected for example side 1 only that has the correct updated values other 3 sides updates with the false values. as my form is dynamic it only shows the field which is selected.
I only want to update the field which is selected, all other has to be null.

I can't see the code you use for updating your data but I can ausme that you probably did not set the merge to true while saving the data.
Take a look at this code snipped:
var cityRef = db.collection('cities').doc('BJ');
var setWithMerge = cityRef.set({
capital: true
}, { merge: true });
By setting that we ensure to udate only the fields we want to and leave the rest as it is. Still make sure not to send fields with a null value because that is a valid value for firestore and it doesn't mean that those fields will by skipped in the update process. You can find more about it here.
Hye i am having a little trouble again i am supposed to put a list of questions in airtable and then print them to my screen but i am working with a fetch reqeust en then e method of get but i have the feeling like my empty variable aren't being filled with my questions
its in javascript btw :
here's my code :
; (function (){
window.addEventListener('load', function(){
document.getElementById('next').addEventListener('click', function(){
window.location.href = 'vragenlijst2.html';
})
let vrg1 = document.getElementById('1vraag');
let vrg2 =document.getElementById('2vraag');
let vrg3 = document.getElementById('3vraag');
let vrg4 = document.getElementById('4vraag');
let vrg5 = document.getElementById('5vraag');
let vrg6 = document.getElementById('6vraag');
let vrg7 = document.getElementById('7vraag');
let vrg8 = document.getElementById('8vraag');
let vrg9 = document.getElementById('9vraag');
let vrg10 = document.getElementById('10vraag');
let Vragenlijst_id = 1;
let getData = function(){
fetch('https://api.airtable.com/v0/appojP2iMG4i3P61S/EDBL', {
method: 'GET',
headers: {
'Authorization' : 'Bearer keyDhD8sLGjcEuA4K'
}
})
.then(Response => Response.json())
.then(JSON => {
console.log(JSON)
for(let index = 0; index < JSON.records.length; index++){
let Qstn = JSON.records[index];
if(Vragenlijst_id === Qstn.fields.vragenlijst){
let vrg1_db = Qstn.fields.Vraag1;
let vrg2_db = Qstn.fields.Vraag2;
let vrg3_db = Qstn.fields.Vraag3;
let vrg4_db = Qstn.fields.Vraag4;
let vrg5_db = Qstn.fields.Vraag5;
let vrg6_db = Qstn.fields.Vraag6;
let vrg7_db = Qstn.fields.Vraag7;
let vrg8_db = Qstn.fields.Vraag8;
let vrg9_db = Qstn.fields.Vraag9;
let vrg10_db = Qstn.fields.Vraag10;
vrg1 = vrg1_db;
vrg2 = vrg2_db;
vrg3 = vrg3_db;
vrg4 = vrg4_db;
vrg5 = vrg5_db;
vrg6 = vrg6_db;
vrg7 = vrg7_db;
vrg8 = vrg8_db;

console.log(vrg1);
}
}

How can I handle request fails in this example of axios.all requests. I.e. if all servers are responde with JSON all is okay and I have JSON file at end of a cycle. But if one of this servers not responde with JSON or not responde at all I do have nothing in "/data.json" file, even all other servers are working perfectly. How can I catch a server fail and skip it?
var fs = require("fs");
var axios = require('axios');
var util = require('util');
var round = 0;
var tmp = {};
var streem = fs.createWriteStream(__dirname + '/data.json', {flags : 'w'});
toFile = function(d) { //
streem.write(util.format(d));
};
start();
setInterval(start, 27000);
function start(){
streem = fs.createWriteStream(__dirname + '/data.json', {flags : 'w'});
monitor();
}
function monitor(){
axios.all([
axios.get('server1:api'),
axios.get('server2:api'),
axios.get('server3:api'),
axios.get('server4:api'),
]).then(axios.spread((response1, response2, response3, response4) => {
tmp.servers = {};
tmp.servers.server1 = {};
tmp.servers.server1 = response1.data;
tmp.servers.server2 = {};
tmp.servers.server2 = response2.data;
tmp.servers.server3 = {};
tmp.servers.server3 = response3.data;
tmp.servers.server4 = {};
tmp.servers.server4 = response4.data;
toFile(JSON.stringify(tmp));
round++;
streem.end();
streem.on('finish', () => {
console.error('Round: ' + round);
});
})).catch(error => {
console.log(error);
});
}
The most standard way to approach this would be a recursive function like below.
let promises = [
axios.get('server1:api'),
axios.get('server2:api'),
axios.get('server3:api'),
axios.get('server4:api'),
];
async function monitor() {
const responses = (arguments.length === 1 ? [arguments[0]] : Array.apply(null, arguments))[0];
const nextPromise = promises.shift();
if (nextPromise) {
try {
const response = await getSentenceFragment(offset);
responses.push(response);
}
catch (error) {
responses.push({});
}
return responses.concat(await monitor(responses));
} else {
return responses;
}
}
monitor([]).then(([response1, response2, response3, response4]) => {
tmp.servers = {};
tmp.servers.server1 = {};
tmp.servers.server1 = response1.data;
tmp.servers.server2 = {};
tmp.servers.server2 = response2.data;
tmp.servers.server3 = {};
tmp.servers.server3 = response3.data;
tmp.servers.server4 = {};
tmp.servers.server4 = response4.data;
toFile(JSON.stringify(tmp));
round++;
streem.end();
streem.on('finish', () => {
console.error('Round: ' + round);
});
});
