I have an object like this:
{
"idMeal": "52795",
"strMeal": "Chicken Handi",
"strDrinkAlternate": null,
"strCategory": "Chicken",
"strArea": "Indian"
}
I am trying to get the value of other items(i.e. strMeal and strCategory) using the value of "idMeal". How can I do that?
As far as i understood you want to filter an list of food objects, just put them in an array and filter like this:
[obj1, obj2, obj3].filter(o => o.idMeal="52795")
First you should have stated what you tried. Then, you can use a simple condition:
let cat;
let area;
if (obj.idMeal === myValue) {
cat = obj.strCategory;
area = obj.strArea;
}
There are way more ways of doing this. Take a look at .map(), .filter() but those are for arrays.
The easiest way to achieve this is to filter the data based on the key-value pair and then reduced the requested fields into a new object.
const mealData = [{
"idMeal": "52795",
"strMeal": "Chicken Handi",
"strDrinkAlternate": null,
"strCategory": "Chicken",
"strArea": "Indian",
}];
const filterAndMap = (data, key, value, fields) =>
data
.filter((record) => record[key] === value)
.map(record => fields.reduce((acc, field) =>
({ ...acc, [field]: record[field] }), {}));
const result = filterAndMap(mealData, 'idMeal', '52795', ['strMeal', 'strCategory']);
console.log(result);Alternatively, you could pass a filter function and a mapper function:
const mealData = [{
"idMeal": "52795",
"strMeal": "Chicken Handi",
"strDrinkAlternate": null,
"strCategory": "Chicken",
"strArea": "Indian",
}];
const filterAndMap = (data, filterFn, mapperFn) =>
data.filter(filterFn).map(mapperFn);
const result = filterAndMap(
mealData,
({ idMeal }) => idMeal === '52795',
({ strMeal, strCategory }) => ({ strMeal, strCategory }));
console.log(result);In the example above, we can remove the filterAndMap function and just chain filter and map directly.
const mealData = [{
"idMeal": "52795",
"strMeal": "Chicken Handi",
"strDrinkAlternate": null,
"strCategory": "Chicken",
"strArea": "Indian",
}];
const result = mealData
.filter(({ idMeal }) => idMeal === '52795')
.map(({ strMeal, strCategory }) => ({ strMeal, strCategory }));
console.log(result);
