Operators

Operators are special language features that alter the normal output of a query or perform a specific function.

Array indexing

As a way to access a specific element inside an array at a given position, we have integrated inside GQ the array indexing syntax. To do so, into an array field, you can specify the desired index enclosed in [].

Given the following input:

input.json

{
  "companies": [
    {
      "name": "Apple",
      "marketCap": 3.286
    },
    {
      "name": "Microsoft",
      "marketCap": 3.206
    },
    {
      "name": "Nvidia",
      "marketCap": 2.866
    }
  ]
}

If we want to obtain the first element in the companies array, we can apply the next query:

query.gq

companies[0]

output.json

{
  "name": "Apple",
  "marketCap": 3.286
}

This is also compatible with the dot operator or any previously explained concept:

query.gq

companies[1].name

output.json

"Microsoft"
