I have the following array below and looking to match all objects that match the string "en-GB". My current implementation results in "Cannot use 'in' operator to search for 'en' in en-GB"
Array:
const filtData = [
[
{
descriptions: {
attrs: {
lang: "en-GB",
},
},
},
{
descriptions: {
attrs: {
lang: "es",
},
},
},
{
descriptions: {
attrs: {
lang: "dk",
},
},
},
],
[
{
descriptions: {
attrs: {
lang: "sp",
},
},
},
{
descriptions: {
attrs: {
lang: "en-GB",
},
},
},
{
descriptions: {
attrs: {
lang: "it",
},
},
},
],
[
{
descriptions: {
attrs: {
lang: "en",
},
},
},
{
descriptions: {
attrs: {
lang: "uk",
},
},
},
{
descriptions: {
attrs: {
lang: "en-GB",
},
},
},
],
];
JS filter:
const res = filtData.map((el) => el.filter((a) => a.descriptions.attrs.lang.some((o) => "en-GB" in o)));
console.log(filtData);
You need to compare the value.
const
filtData = [[{ descriptions: { attrs: { lang: "en-GB" } } }, { descriptions: { attrs: { lang: "es" } } }, { descriptions: { attrs: { lang: "dk" } } }], [ { descriptions: { attrs: { lang: "sp" } } }, { descriptions: { attrs: { lang: "en-GB" } } }, { descriptions: { attrs: { lang: "it" } } }], [{ descriptions: { attrs: { lang: "en" } } }, { descriptions: { attrs: { lang: "uk" } } }, { descriptions: { attrs: { lang: "en-GB" } } }]],
result = filtData.map(a =>
a.filter(({ descriptions: { attrs: { lang } } }) => lang === "en-GB")
);
console.log(result);.as-console-wrapper { max-height: 100% !important; top: 0; }
