I have an array like so with a single object inside:
FirstArray = [{
"category": "None",
"ARFE": 553.5,
"BV": 900,
"RF rfeer": 0,
.....
}]
I want to convert it so that every key-value pair (where the value is a number) in the object is in its own object like the following:
NewArray = [{
name: "ARFE",
value: 553.05
}, {
name: "BV",
value: 900
}, {
name: "RF rfeer",
value: 0
}, .....]
Here, each key was assigned a new key called name, and the value for the original key was assigned a new key called value. Those pairs are then put into their own object inside the array.
Note that "category": "None" is not its own object in the array since "None" is non-numerical.
It's also important to note that there could be many key-value pairs, so it's not just limited to the items above (e.g., "ARFE": 553.5, etc.)
What I have so far:
I know you can separate a single object into multiple objects:
NewArray = Object.entries(FirstArray).reduce((prev, [og, nw]) => {
let [name, value] = og.match(/\D+|\d+$/g)
prev[value] = { ...(prev[value] || {}), [name]: nw }
return prev;
}, {})
I also know how that you can create a new object with new keys like so:
NewArray = Object.assign(
...Object.entries(FirstArray).map(([key, value]) => ({ [key]: name }))
);
However, I'm having trouble putting everything together. How would I be able to achieve NewArray from FirstArray?
You were pretty close. All you needed to do is specify the name:
const data = {
"category": "None",
"ARFE": 553.5,
"BV": 900,
"RF rfeer": 0
};
const result = Object
.entries(data)
.filter(([_, value]) => typeof value === 'number')
.map(([key, value]) => ({ name: key, value }));
console.log(result);Also, if you don't want { "name": "category", "value": "None" } to be included in the result, you can just filter it:
const result = Object
.entries(data)
.filter(([ key ]) => key !== 'category')
.map(([key, value]) => ({ name: key, value }));
