I have an object that contains other objects, as well as a few numbers i don't want.
I want to convert the object into an array of objects and remove the numbers.
an example:
INPUT
const object = {
john: {
instrument: 'violin',
age: 26
},
bob: {
instrument: 'guitar',
age: 32
},
numberIDontWant: 2,
flynn: {
instrument: 'piano',
age: 3
},
numberIDontWant2: 9
}
OUTPUT
[
{
name: 'john',
instrument: 'violin',
age: 26
},
{
name: 'bob',
instrument: 'guitar',
age: 32
},
{
name: 'flynn',
instrument: 'piano',
age: 20
}
]
Can anyone help me with that?
You could use Object.entries and .map:
console.log(Object.entries({
john: {
instrument: 'violin',
age: 26
},
bob: {
instrument: 'guitar',
age: 32
},
numberIDontWant: 2,
flynn: {
instrument: 'piano',
age: 3
},
numberIDontWant2: 9
}).map(([k,v]) => typeof v === 'object' ? ({...v, name: k}) : undefined).filter(i => i))You'll most likely want to iterate over the Object.entries() so you have access to the key (the name) and the value. It isn't 100% clear what the criteria is for what values to include/exclude, but one way would be to only include the values that have a typeof equal to 'object'.
function objectToArray(obj) {
let arr = [];
for (let [name, value] of Object.entries(obj)) {
if (typeof value === "object") {
arr.push({
...value,
name,
});
}
}
return arr;
}
console.log(
objectToArray({
john: {
instrument: "violin",
age: 26,
},
bob: {
instrument: "guitar",
age: 32,
},
numberIDontWant: 2,
flynn: {
instrument: "piano",
age: 3,
},
numberIDontWant2: 9,
})
);You could use map and filter
const data = {
john: {
instrument: 'violin',
age: 26
},
bob: {
instrument: 'guitar',
age: 32
},
numberIDontWant: 2,
flynn: {
instrument: 'piano',
age: 3
},
numberIDontWant2: 9
}
const result = Object.entries(data).map(([k, v]) => {
if (typeof v === "object") return { ...v, name: k }
}).filter(x => x);
console.log(result);
