How to declare multi-line arrays in yaml with examples

YAML Arrays example

Arrays are a group of fixed-size elements. Array elements in the YAML file contain separate lines, Also called multiline array strings.

In YAML, array syntax is

let’s declare an array in any programming languages

["admin", "finance", "hr"]

Above written with yaml sequence also

---
- admin
- finance
- hr

Let’s declare the key and value as an array in YAML.

roles contain an array of admin, HR, and sales, finance

We have to use a sequence with key=roles, and the value is a multi-line array of strings.

Here is an example of the YAML sequence that is the same as multi-line strings.

---
roles:
- admin
- finance
- hr
- sales

Also, this can be represented in multiple ways

"roles":["admin","finance","hr","sales"]

This is good as it is very easy to read and understand. or

"roles":["admin","finance","hr",
    "sales"]

Suppose you have a list of employee objects in json that contain an array of arrays.

{
  "employees": [
    [
      "emp1",
      "emp2",
      "emp3"
    ],
    [
      "emp11",
      "emp12",
      "emp13"
    ]
  ]
}

YAML represents an array of arrays as follows

---
employees:
- - emp1
  - emp2
  - emp3
- - emp11
  - emp12
  - emp13
