How to append JSON object to JSON object? [duplicate] - javascript

This question already has an answer here:
Dynamic object property names?
(1 answer)
Closed 8 months ago.
so i have this JSON file:
{"fjord-200-200.jpg":[]}
I read it using
let data = fs.readFileSync(cachedName);
let cachedInJSON: JSON = JSON.parse(data.toString());
so i have now JSON object, that i want to append to this new JSON object
let newData = {
fileNameFormatted: []
}
when i tried using
let newJson = {...cachedInJSON, ...newData}
Result was this:
{"fjord-200-200.jpg":[],"fileNameFormatted":[]}
Wanted result that i want to achieve is:
{"fjord-200-200.jpg":[],"fjord-300-300.jpg":[]}
fileNameFormatted is a variable holding fjord-300-300.jpg


let newData = {
[fileNameFormatted]: [] // Notice the brackets around the key
}

data[0].ImageSets[0].ImageSet.forEach((image) => {
var images = image.LargeImage[0].URL[0]
console.log(images)
})
I'm getting all URL's in console log.
I tried to merge them with split() but it's not working. Each string is getting its own array. Similarly if i use var images = image.LargeImage[0].URL. Each string return it's own array.
What i want is a single array with all URL's like this.
["https://images-na.ssl-images-amazon.com/images/I/41NeQS3RMzL.jpg", "https://images-na.ssl-images-amazon.com/images/I/316W1tHrMuL.jpg", "https://images-na.ssl-images-amazon.com/images/I/31TgrPVXYjL.jpg", "https://images-na.ssl-images-amazon.com/images/I/51qcfjgaAZL.jpg", "https://images-na.ssl-images-amazon.com/images/I/41numbb3sgL.jpg", "https://images-na.ssl-images-amazon.com/images/I/41PLx0E2sqL.jpg","https://images-na.ssl-images-amazon.com/images/I/41bz4b5IbLL.jpg"]
Thanks.

It makes more sense here to just use .map(), as it will create a new Array with the return value of each iteration

This is how you would do it with .forEach(), additionally
var

How can I get a key from an object by its value? [duplicate]

This question already has answers here:
How to get a key in a JavaScript object by its value?
(31 answers)
Closed 3 years ago.
I am working in react. I have a constant like
const priorityMap = {
"medium":"clean",
"high":"breaker",
"low":"promote"
}
If I do the following , I am getting result.
const map1 = priorityMap["medium"];
console.log("print checkgroup " + map1)
But I want to do the reverse thing. My input is "clean" and I want to retrieve "medium". Is there any way to fetch the key?

It would be :
const valueToSearch = "clean"
const result = Object.entries(priorityMap).find(entry => entry[1] === valueToSearch)[1]

Unable store the objects into an array in javascript [duplicate]

Does JavaScript pass by reference? [duplicate]

Closed 3 years ago.
I'm trying to store the objects into Javascript array.
var res=[
{name:'Alex',place:'US',age:20},
{name:'Jason',place:'Canada',age:25}
];
var obj={};
var data=[];
for ( let i in res){
obj.name=res[i].name;
obj.place=res[i].place;
data.push(obj);
}
console.log(data);
My expected output:
[
{name:'Alex',place:'US'}.
{name:'Jason',place:'Canada'}
]
Actual output I got:
[
{name:'Jason',place:'Canada'},
{name:'Jason',place:'Canada' }
]
Why I'm getting this type of output?
I'm noobie.Please help me.

You only have one object in memory with your var obj={}; - that line runs once, and creates one object in memory, which you then proceed to mutate on every iteration in the for loop, and push to the array. At the end, the array contains 2 references to the same object.
Create the object inside the loop instead:
for ( let i in res){
var obj = {};
obj.name=res[i].name;
obj.place=res[i].place;
data.push(obj);
}
You could also consider using .map instead:
const res=[
{name:'Alex',place:'US',age:20},
{name:'Jason',place:'Canada',age:25}
];
const data = res.map(({ name, place }) => ({ name, place }));
console.log(data);

You are basically updating the same object again and again in your loop. You need to have different objects for each loop. Hence, you need to move var obj={} inside the for loop.
var res=[{name:'Alex',place:'US',age:20},{name:'Jason',place:'Canada',age:25}];
var data=[];
for ( let i in res){
var obj={};
obj.name=res[i].name;
obj.place=res[i].place;
data.push(obj);
}
console.log(data);

Using .map would be much easier
var res=[
{name:'Alex',place:'US',age:20},
{name:'Jason',place:'Canada',age:25}
];
var obj={};
var data = res.map(({ name, place }) => {
return ({ name, place })
});
console.log(data);

Add multiple options in array with javascript [duplicate]

How can I add a key/value pair to a JavaScript object?

Closed 7 years ago.
I have this var
var allwords = {};
And i need push more options in this array like:
allwords.push = {"Ctrl-Space": "autocomplete"};
allwords.push = {"Ctrl-pause": "closewindow"};
And look like this:
allwords = {"Ctrl-Space": "autocomplete", "Ctrl-pause": "closewindow"};
How can't i do?

push is for Array objects. For traditional objects, assign the properties manually like
var allwords = {};
allwords["Ctrl-Space"] = "autocomplete";
allwords["Ctrl-pause"] = "closewindow";
console.log(allwords);

javascript convert array to json object [duplicate]

JavaScript: Converting Array to Object
(2 answers)
Closed 8 years ago.
I've got the following array:
array = [{"id":144,"price":12500000},{"id":145,"price":13500000},
{"id":146,"price":13450000},{"id":147,"price":11500000},
{"id":148,"price":15560000}]
i wanto convert it to json like this:
json = {{"id":144,"price":12500000},{"id":145,"price":13500000},
{"id":146,"price":13450000},{"id":147,"price":11500000},
{"id":148,"price":15560000}}
So than i can store everything in mongodb in a unique document.
Regards,

Just run a loop and equate...like...
var obj = {};
for(var i=0; i<array.length; i++)
{
obj[i] = array[i]
}
It will do
{
0:{"id":144,"price":12500000},
1:{"id":145,"price":13500000},
2:{"id":146,"price":13450000},
3:{"id":147,"price":11500000},
4:{"id":148,"price":15560000}
}
Because your JSON is invalid.

Not sure what you are asking
From array or another variable to json string =>
var str = JSON.stringify(thing);
From a json string to variable
var thing = JSON.parse(str);
