Filter a two-dimensional array based on the presence of a string value found in the second array

My logic for this assignment is not very good, as I need to filter a 2D array based on the values of another array.

Let me provide an example of the 2-Dimensional Array:

const roles = [ ['roles', 'admin', 'write'], ['roles' ,'admin', 'read'], ['roles', 'member', 'read']]

I am looking to filter the array to only include elements that contain 'member'. The desired result would be:

const result = ['roles', 'member', 'read']

Any tips on how I can accomplish this task?

Answer №1

const roles = [ ['roles', 'admin', 'write'], ['roles' ,'admin', 'read'] ,['roles', 'member', 'read']]
const answer = roles.find(arr => arr.some((e) => e === "member"));
console.log(answer)
To find multiple arrays containing the string "admin", you can use filter instead of find in the code above.

Answer №2

Found a quick solution by hydrating with water and clearing my mind hahahaha

here's the resolution

const result = roles.filter(
  (dt) => dt[1] === 'member'
);
