'''Works with gojq, the Go implementation of jq'''

Assuming the input is a single array of arrays, we can simply chain the `add` and `unique` filters:

<lang jq>jq -nc '[[5,1,3,8,9,4,8,7], [3,5,9,8,4], [1,3,7,9]] | add | unique'</lang>

{{out}}

<pre>

[1,3,4,5,7,8,9]

</pre>

If the arrays are presented individually in an external stream, we could use the `-s` command-line option.

Alternatively, here's a stream-oriented version of `add` that could be used:

<lang jq>def add(s): reduce s as $x (null; . + $x);</lang>

For example:

<lang jq>jq -nc '

def add(s): reduce s as $x (null; . + $x);

add(inputs) | unique' <<< '[5,1,3,8,9,4,8,7] [3,5,9,8,4] [1,3,7,9]'</lang>
