Javascript recreate multidimensional array [duplicate]

Question

I have the following multidimensional array stored in a variable named posts

{ID: 141, categories: ["candy", "fruits", "vegetables"]}
{ID: 142, categories: ["fruits"]}
{ID: 143, categories: ["candy", "vegetables"]}

Is it possible to create a new array only with items containing candy in the categories?

So the new posts variable will have the following array:

{ID: 141, categories: ["candy", "fruits", "vegetables"]}
{ID: 143, categories: ["candy", "vegetables"]}

yes it is possible, what have you tried?

You can use filter() and includes() methods and return new array.

const data = [{ID: 141, categories: ["candy", "fruits", "vegetables"]}, {ID: 142, categories: ["fruits"]}, {ID: 131, categories: ["candy", "vegetables"]}]

const result = data.filter(({categories}) => categories.includes('candy'));
console.log(result)
