I'M TRYING TO HANDLE THIS DATA IN JAVASCRIPT SO HOW CAN I REMOVE DATA ACCORDING TO THE ID NUMBER THE FIRST NUMBER
600030/01/2018/163904
600010/01/2014/3789
600030/01/2020/47104
600030/01/2012/39104
600010/01/2011/93817
how can i remove all 600030 data so i get
600010/01/2014/3789
600010/01/2011/93817
If all data shaped in Array and element is instance of String.
I would recommend Array.prototype.filter and String.prototype.startsWith();
let data = [
'600030/01/2018/163904',
'600010/01/2014/3789',
'600030/01/2020/47104',
'600030/01/2012/39104',
'600010/01/2011/93817',
];
let filteredData = data.filter((d)=>!d.startsWith('600030'));
console.log( filteredData );
Result is
[
'600010/01/2014/3789',
'600010/01/2011/93817'
]

I'm trying to add a new item (a placeholder) to an array -- to each node
My array looks as follow:
And I wanna add the following key/value under value Year: "2010"
I have tried *json1.push("Year", "2010")* but that just creates a new entry
If you want to add it to the first object on the array, use
json1[0]["year"] = "2010"

var charArray=[a,b,c]
I want to have a new array as following:
var charArrayNew=[a, ab, abc]
Please suggest how to get the result of charArrayNew in ES6 Javascript.
You could do this:
const charArray=['a','b','c'];
const answer = charArray.map((_,i,ar)=>ar.slice(0,i+1).join(""));
console.log(answer);
// or, alternatively:
fn=(ar,res=[])=>(
ar.reduce((a,c)=>(res.push(a+=c),a),""),res );
console.log(fn(charArray))

I am working with an array in Javascript that contains several IDs in them but I would like to filter out all non-numeric entries using regex and return that array of just numbers. For example, I have myArray = ['131125150138677','CI%20UW%20SYSTEMS%20S','040964100010832'] where I want to get rid of the second item in the list since it's non-numeric.
So use Filter and test to see if they are numbers
var myArray = ['131125150138677', 'CI%20UW%20SYSTEMS%20S', '040964100010832']
var filtered = myArray.filter(Number)
console.log(filtered)
var filtered2 = myArray.filter(s => s.match(/^\d+$/))
console.log(filtered2)

I am integrating jqbarGraph, the demo worked fine. I want to make the values dynamic.
this is my json response
{"success":false,"message":{"12":7887,"11":159}}
I need an array like this
graphByMonth = new Array(
[7887,12],
[159,11]
);
Need to create dynamic array from JSON data.
Does this work?
var graphByMonth = [],
jsonResponse = {"success":false,"message":{"12":7887,"11":159}},
data = jsonResponse.message;
Object.keys(data).forEach(function (k, i ) {
graphByMonth.push([data[k],+k]);
});
console.log(graphByMonth);
