Probably yes if you have learned programming starting with procedural languages. There is a steep learning curve in the beginning but even if you will not use APL for "normal" projects, the way an array programming language makes you think about data transformations is worth the effort. And it is also quite practical for smaller to medium tasks involving mainly mathematical operations, e.g. data analytics. Not so for mainstream / web / systems etc. After having a grip on the notation, I would say the time/effort to put an algorithm or idea into code is probably comparable to other languages (if not less).
