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 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 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!"});

I want to do REST api to my clients.
Should I return my data wrapped as an object or just the data? what are the guidelines?
for /products:
This:
res.json({ products: [{ ... }] });
or that:
res.json([{ ... }]);
If you have only one object to respond then in this scenario you can use this
res.json([{ ... }]);
but if you have multiple object to return then you can use this
res.json({ products: [{ ... }], products2: [{ ... }] });

For example if we have:
let r = JSON.parse('{"o": {"name": "foo","lastName": "boo"}}');
Can we now do console.log(r.o.name); and get foo on the console?
Yes. Here's a runnable example:
let r = JSON.parse('{"o": {"name": "foo","lastName": "boo"}}');
console.log(r.o.name)
