I have two JSON objects and I'm planning to join them.
obj1 = [{'foo': 'bar', 'foo1': 'bar1'}];
obj2 = [{'foo2': 'bar2'}];
objFinal = [
{
"foo": "bar",
"foo1": "bar1",
"title":
[
{ "foo2": "bar2" }
]
}
]
My plan is to get the result the same as objFinal. I've used .concat but it didn't returned the result I wanted. What are other options I can do to get the result as same as objFinal?
Please use this code.
objFinal = [{ ...obj1[0], title: obj2}];

I have a following data, and I want to convert to list of array without key.
How do I do it?
Data
[{
"time": "01/13 15:50",
"price": 3000,
"changeRate": -0.27
},
{
"time": "01/13 15:40",
"price": 4000,
"changeRate": -0.27
}]
Desired output
[
[01/13 15:50, 3000],
[01/13 15:40, 4000]
]
Thank you in advance!
You can use the map method for that. It's used to transform (or "map") one array into a new one. The new array has the same length as the original, and its items are derived from the items in the original array.
data.map(item => [item.time, item.price]);

I want to push an item into an array that in that have objects in them, like this:
var testarray = [
{
first: "See this?",
second: "Oh my!"
},
{
first: "Nice!",
second: "Amazing!"
}
]
You can see that I for this variable/array, I can't just use this testarray.push("Wonderful!"). Please show me how I can push things into these sort of arrays.
The "multiple things" are objects. Push another object in the same format.
testarray.push({first: "Wow!", second: "Wonderful!"});

How can I get the first value of json object? The object contains dynamic values and I need always first value of the object
errors = {
state: [ 'The state field is required.' ],
city: [ 'The city field is required.' ]
}
You can use Object.values.
let firstValue = Object.values(errors)[0]

I have 2 arrays with objects:
first = {
a:false,
b:false,
c:false,
d:false
}
second = {
a:true,
c:true
};
I want to get:
third = {
a:true,
b:false,
c:true,
d:false
}
I'm using underscore and jQuery.
I tried _.union but it returns an array with all the indexes of a&b.
It seems like your're looking for underscore's defaults function
var third = _.defaults(second, first);
// Object {a: true, b: false, c: true, d: false}
