get value from array of object

Question

I am having trouble accessing elements of an array. I want to assign project name to local variable projectName can anyone help me solve how to get the project name from the json structure described above? Thank you

Assuming the array is called input: input[0].project.name for 'Example123', input[1].project.name for 'test' and input.map(item => item.project.name) for ['Example123', 'test']. — Barremian

Adding the actual JSON instead of a screenshot would be more helpful. — RobMac

You can use array map and return.

let data = [{...}, {...}];
let projectNames = data.map(item => {
    return item.project.name;
});

Your return value will be an array of strings

["Example123", "test"]

Assuming that you JSON is something like this:

data = [
  {
    project: {
      coverUrl: null,
      description: null,
      id: 'some-guid-1',
      name: 'Example123'
    }
  },
  {
    project: {
      coverUrl: null,
      description: null,
      id: 'some-guid-2',
      name: 'test'
    }
  }
]

Then accessing and assigning a project name would require the position, plus the properties:

var projectName = data[0].project.name // 'Example123'
