I have this code - its a bit tricky:
let i = 0;
const inputBuffer = [];
const randomnumber = (min, max) => {
return Math.floor(Math.random() * (max - min + 1) + min);
}
for (let k = 0; k < 10; k++) {
console.log(convert(randomnumber(0, 1982)));
}
function convert(input) {
inputBuffer.push(input);
const output = {"current" : "0"};
if (i % 3 == 0) {
let sum = 0;
for (let ii = 0; ii < i; ii++) {
sum += inputBuffer[ii];
}
output.sum = sum;
}
i++;
output.current = input;
return JSON.stringify(output);
}
The output looks like this:
{"current":605,"sum":0}
{"current":708}
{"current":456}
{"current":1838,"sum":1769}
{"current":1619}
{"current":1404}
{"current":1068,"sum":6630}
{"current":1178}
{"current":989}
{"current":1280,"sum":9865}
But I want it to look like this:
{"current": 605}
{"current": 708}
{"current": 456}
{"current": 1838,"sum":1769}
{"current": 1619}
{"current": 1404}
{"current": 1068,"sum":6630}
{"current": 1178}
{"current": 989}
{"current": 1280,"sum":9865}
let i = 0;
const inputBuffer = [];
const randomnumber = (min, max) => {
return Math.floor(Math.random() * (max - min + 1) + min);
}
for (let k = 0; k < 10; k++) {
console.log(convert(randomnumber(0, 1982)));
}
function convert(input) {
inputBuffer.push(input);
const output = {
"current": "0"
};
if (i % 3 == 0) {
let sum = 0;
for (let ii = 0; ii < i; ii++) {
sum += inputBuffer[ii];
}
output.sum = sum;
}
i++;
output.current = input;
return JSON.stringify(output);
}I don't want to show the sum the first time but later show it every 3 times
Got any ideas? :D
PS. I prefer staying basic and only use a for loop
Have a nice evening
Could you just check if i is not zero when you assign the value of output.sum ?
Something like the following:
let i = 0; const inputBuffer = []; const randomnumber = (min, max) => { return Math.floor(Math.random() * (max - min + 1) + min); } for (let k = 0; k < 10; k++) { console.log(convert(randomnumber(0, 1982))); } function convert(input) { inputBuffer.push(input); const output = {"current" : "0"}; if (i % 3 == 0) { let sum = 0; for (let ii = 0; ii < i; ii++) { sum += inputBuffer[ii]; } if (i !== 0) output.sum = sum; // HERE } i++; output.current = input; return JSON.stringify(output); }I found this out, yours is obviously shorter but here was my Idea :D
let i = 0;
const inputBuffer = [];
let db = false;
const randomnumber = (min, max) => {
return Math.floor(Math.random() * (max - min + 1) + min);
}
for (let k = 0; k < 10; k++) {
console.log(convert(randomnumber(0, 1982)));
}
function convert(input) {
inputBuffer.push(input);
const output = {"current" : "0"};
if (db && i % 3 == 0) {
let sum = 0;
for (let ii = 0; ii < i; ii++) {
sum += inputBuffer[ii];
}
output.sum = sum;
}
i++
db = true;
output.current = input;
return JSON.stringify(output);
}
