I'm starting with an array of objects, such as
const data = [
{
data1: 124,
data2: 5332,
data3: 12,
},
{
data1: 642,
data2: 5,
data3: 798,
}
]
I would like to filter the array of objects down to just the "data2" key, like this...
[
{
data2: 5332
},
{
data2: 5,
}
]
I tried with this code:
const key = "data2";
const filtered = data.filter((d) => Object.keys(d.data) === key )
And have tried variants of this filter. I know I can use data.forEach but was wondering if there is any way to accomplish this using filter
What you want is
const filtered = data.map((d) => ({
[key]: d[key]
}));
Working snippet:
const data = [{
data1: 124,
data2: 5332,
data3: 12,
},
{
data1: 642,
data2: 5,
data3: 798,
}
]
const key = "data2";
const filtered = data.map((d) => ({
[key]: d[key]
}));
console.log(filtered);
