I have that array of dict:
arrayDict: [
{
Description: "Dict 0"
Category: [
'First',
'Both',
],
},
{
Description: "Dict 1",
Category: [
'Second',
'Both',
],
},
]
i would like to filter inside that array by Category. i will recieve a category and i need to filter. If i recieve "Both", i need to return "Dict 1" and "Dict 0". if i receive "Second", i return only "Dict 1".
How can i do that?
You can achieve your goal by using filter method, like this:
const arrayDict = [
{
Description: "Dict 0",
Category: [
'First',
'Both',
],
},
{
Description: "Dict 1",
Category: [
'Second',
'Both',
],
},
];
const filterDict = (key)=> arrayDict.filter(({Category}) => Category.includes(key))
console.log('First:',filterDict('First'));
console.log('Second:',filterDict('Second'));
console.log('Both:',filterDict('Both'));somthing like this:
arrayDict.filter((item)=> item.Category.includes('Both'))
you can simply use the filter() : higher order function provided by JS.
var arrayDict = [
{
Description: "Dict 0",
Category : [
'First',
'Both',
]
},
{
Description: "Dict 1",
Category : [
'Second',
'Both',
],
},
]
let input = 'Both';
let filteredData = arrayDict.filter((elm) => {
return elm.Category.includes(input)
})
console.log(filteredData);
