             Summary: [JS] Create table from Arrays
                 Key: ARROW-7109
                 URL: https://issues.apache.org/jira/browse/ARROW-7109
             Project: Apache Arrow
          Issue Type: Wish
            Reporter: Sascha Hofmann


I am trying to generate an arrow table from JS arrays and followed the example from [here|[https://observablehq.com/@lmeyerov/manipulating-flat-arrays-arrow-style]] but I am struggling to generate different schemas, most importantly how to provide a type different then 'floatingpoint'. Right now, I have:
{code:java}
const data = Table.from({    schema: {      fields: [        {          name: 'a',          nullable: false,          children: Array(0),          type: {            name: 'floatingpoint',            precision: 'SINGLE'          }        }      ]    },    batches: [      {        count: 10,        columns: [          { name: 'a', count: 10, VALIDITY: [], DATA: Array.from({ length: 10 }, () => 'a') }        ]      }    ]  })
{code}
Which, of course is non-sense but I couldn't figure out how to provide the type (I tried type: Utf8 among others). 

On another note, are there any plans to make the docs a little bit more descriptive? Happy to contribute!
