I’d like to make this array:
[
{main: "material", value: "blend"},
{main: "material", value: "synthetic"},
{main: "style", value: "curl"},
{main: "style", value: "bob"},
{main: "material", value: "premium"}
]
to this:
{
material: ["blend", "synthetic", "premium"],
style: ["curl", "bob"]
}
I used two "FOR" but it didn’t work out well:( Quite newbie in Javascript🥲
>Solution :
You can use reduce to have that result
const data = [{
main: "material",
value: "blend"
}, {
main: "material",
value: "synthetic"
}, {
main: "style",
value: "curl"
}, {
main: "style",
value: "bob"
}, {
main: "material",
value: "premium"
}]
const finalResut = data.reduce((result, currentData) => {
const {
main,
value
} = currentData
if (!result[main]) {
result[main] = []
}
result[main].push(value)
return result
}, {})
console.log(finalResut).as-console-wrapper {
max-height: 100% !important;
top: 0;
}
