"Creating an array" is topic seldom discussed in J as all data in J is an array, and every verb takes array argument(s) and returns an array result. For example, in J, the value '''3''' is an array with zero dimensions where the value '''4 5''' is an array with one dimension (this list has 2 elements), as is the empty string '''<nowiki>''</nowiki>''' (this list has 0 elements). |
