Retrieve a specific object element in Javascript using its unique id

Presenting this specific item :

      const list = {
        id: 5,
        name: "customer name",
        projects: [
          {
            id:2, 
            title: "My project One",
            studies: []
          },
          {
            id:4,
            title: "My project Two"
          }
        ]
      }

I am interested in accessing a particular project within this object. Although there are only two projects currently, we anticipate there may be more in the future. How can I retrieve a specific project based on its ID? Please advise on how to accomplish this task. Thanks

Answer №1

In the comments, you mentioned that the data comes from an API. Upon receiving the data, you have the option to remap it so that instead of a list of projects, it becomes an object with keys based on the id field, which I presume is unique.

const allProjects = list.projects.reduce(
    (collected, current) => {
      return { ...collected, ...current };
    }, {})

If that doesn't work, you can also utilize Array's filter method to locate the specific project you need:

const idToFind = 4;
const project = list.projects.filter( project => project.id === idToFind );
