I hope it is not a stupid question. My array looks like this:
const data = [
{
pollType: "1",
pollName: "Can you help me?",
options: [
{ Options: "Yes, I can", PID: "oFnxh-NDdcP" },
{ Options: "No way!", PID: "d9A10-omlUd" }
]
}
];
But I need to have it:
const result = [
{
pollType: "1",
pollName: "Can you help me?",
option1: "Yes, I can",
pid1: "oFnxh-NDdcP",
option2: "No way!",
pid2: "d9A10-omlUd"
}
];
Please don't get angry if it is so simple to do. I highly appreciate your help and if you do a an example so myself and other people can find it very useful in a future...
var orig = [{"pollType":"1","pollName":"Can you help me?","options":[{"Options":"Yes, I can","PID":"oFnxh-NDdcP"},{"Options":"No way!","PID":"d9A10-omlUd"}]}]
var newArr = [];
orig.forEach(v => {
var newObj = {};
newObj.pollType = v.pollType;
newObj.pollName = v.pollName;
v.options.forEach((k, i) => {
newObj["options" + (i + 1)] = k.Options;
newObj["pid" + (i + 1)] = k.PID;
});
newArr.push(newObj);
});
console.log(newArr);

I have an array of words in a .json file
Like this:
[
"city",
"river",
"car"
]
And i want to get an object for each word
Something like this:
[
{
word: "city",
something: "..."
},
{
word: "river",
something: "..."
},
{
word: "car",
something: "..."
}
]
What is the best way to do this?
let new_array = [];
for(let item of old_array)
{
new_array.push({word:item, something:"..."});
}

Group javascript array items on value
Assuming you have a json object like:
[
{
prNumber: 20000401,
text: 'foo'
},
{
prNumber: 20000402,
text: 'bar'
},
{
prNumber: 20000401,
text: 'foobar'
},
]
Is it possible to perform a "join" on prNumber?
For example, maybe the desired output would be something like:
[
{
prNumber: 20000401,
text: [
'foo',
'foobar'
]
},
{
prNumber: 20000402,
text: [
'bar'
]
}
]
I have no code samples worth anything, so I will not post them here.
This would preferrably use vanilla javascript, but will accept a jQuery answer.
You should iterate the initial array and create new objects keyed off the prNumber. Here's how to do it using reduce (assuming you've assigned the array to a variable named orig):
var result = orig.reduce(function(prev, curr, index, arr) {
var num = curr["prNumber"];
if (!prev[num]) {
prev[num] = [];
}
prev[num].push(curr["text"]);
return prev;
}, {});
You can easily convert this into the example structure outlined in your question.

Below JSON Object needs to be iterated and need result as below.
[
{"Aazam":1, "Jagannath":2, "Bharath Kumar M":4 },
{"Bharath Kumar M":1, "Syad":1 },
{"Bharath Kumar M":2 }
]
output needed (can be in map):
Aazam: 1
Jagannath: 2
Bharath Kumar M: 4, 1, 2
Syad: 1
I tried with ES 6 syntax, I am able to get key and values but I am not successful in forming the array as needed.
Solution should be generic.
You can have a object as a output with the unique keys and values for each key as an array that holds the values of all similar keys.
var arr = [{
"Aazam": 1,
"Jagannath": 2,
"Bharath Kumar M": 4
},
{
"Bharath Kumar M": 1,
"Syad": 1
},
{
"Bharath Kumar M": 2
}
];
var res = arr.reduce((acc, item) => {
var keys = Object.keys(item);
keys.forEach((key) => {
if (!acc[key]) {
acc[key] = [];
}
acc[key].push(item[key]);
});
return acc;
}, {});
console.log(res);

What is the best way to convert:
["Isolated-1", "SVT_FedPortGroup", "SVT_StoragePortGroup", "VM Network", "test-pg-2002"]
and this :
["target_Isolated-1", "target_SVT_FedPortGroup", "target_SVT_StoragePortGroup","target_VM Network" ,"target_test-pg-2002"];
to:
"NetworkMaps": [
{
"ENVID": null,
"SourcePG": "Isolated-1",
"TargetPG": "target_Isolated-1"
},
{
"ENVID": null,
"SourcePG": "VM Network",
"TargetPG": "target_SVT_FedPortGroup"
}...
]
I need to to merge two array with respective values.
For example
arr1 : ["a", "b", "c"];
arr2 : ["apple", "ball", "cat"];
result : [{source: "a",target: "apple"}, {source: "b",target: "ball"},{source: "c",target: "cat"}]
Just map them per index (if they have the same length) in a simple loop. Here is a demo:
a = ["Isolated-1", "SVT_FedPortGroup", "SVT_StoragePortGroup", "VM Network", "test-pg-2002"]
b = ["target_Isolated-1", "target_SVT_FedPortGroup", "target_SVT_StoragePortGroup", "target_VM Network", "target_test-pg-2002"]
c = {
"NetworkMaps": []
}
for (var i = 0; i < a.length; i++) {
c.NetworkMaps.push({
"ENVID": null,
"SourcePG": a[i],
"TargetPG": b[i]
})
}
console.log(c);

I got an array of objects of the following form:
let postArray = [
{
id = 1,
body = "some text"
},
{
id = 2,
body = "some other text"
}
]
which I want to rearange to the following form:
{
posts: {
1: {
id = 1,
body = "some text"
},
2: {
id = 2,
body = "some other text"
}
}
}
How can I do that using ES6?
You can reduce your array:
let postArray = [
{
id: 1,
body: "some text"
},
{
id: 2,
body: "some other text"
}
]
const posts = postArray.reduce((acc, b) => ({...acc, [b.id]: b}), {})
const result = { posts }
