At this point you should understand:
- the terms adverb and conjunction
- how to evaluate sentences with adverbs and conjunctions
- how to select subarrays from arrays
- how to modify subarrays in arrays
- boxed data
- hooks and forks
- tacit definition
Check your understanding by doing the following exercises:
- experiment with dyads { {. }. (negative numbers in the left arguments)
- look up a. in the J Dictionary and use it as the right argument in experiments with the dyads { {. }.
- experiment with the adverbs and conjunctions introduced so far
- experiment with the hook = <. , determine what it does and why it does it (hint: give it a name and apply it to 2 4 5.2 7 6.5)
- do the same with the hook = +
