I have data in array
var dataArray = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, ... , 998, 999, 1000];
if i want to select data to show 10 times in each time I want to show 100 data in arrays
First time show output
1, 2, 3, 4, 5, 6, 7, 8, 9, 10 , ..., 100
Second time show output
101, 102, 103, 104, 105 , ..., 200
.
.
.
tenth time show output
901, 902, 903, 904, 905, ..., 1000
Which function can help me or other way can help me (Node Js)?
please try this code and feel free to adapt it according to your NodeJS requirements.
Best,
//Init array
var initArray = function(count){
var res = [];
for (var i = 0; i < count; i++) {
res.push(i+1);
}
return res;
};
var myArray = initArray(1000);
var idx = 0, cutVal = 100;
var showMe = function(){
var print = '';
for (var i = idx; i < (idx + cutVal); i++) {
print = print + myArray[i] + ', ';
}
console.log(print);
idx = idx + cutVal;
};
showMe();
showMe();
showMe();
let sidx = 0;
let size = 100;
let results = [];
function divide() {
for(let i = sidx; i < (sidx + size) && i < dataArray.length; i++){
results.push(data[i]);
}
sidx += size;
//showData of result
process.nextTick(divide);
}
const p = (arr, n) => {
let portion, start = 0;
while ((portion = arr.slice(start, start + n)).length) {
console.log(portion.join(','));
start += n;
}
};
const inputA = Object.keys([...Array(30)]);
p(inputA, 10);
