Why does Knex.js return max('value') as an array?

Question

I want to find max value from a table:

knexClient
    .queryBuilder()

    .withSchema('myschema')
    .from('mytable')
    .where({some_query})
    .max('value');

It returns the needed value as an array with a single element: [{max: 1000}]

Why does it return an array, not just a number, or an object?

Answer 1

knexClient
    .queryBuilder()

    .withSchema('myschema')
    .from('mytable')
    .where({some_query})
    .max('value')
    .first(); // Add this to get an object
