APL vs Visual Basic
When comparing APL vs Visual Basic, the Slant community recommends APL for most people. In the question“What is the best programming language to learn first?” APL is ranked 55th while Visual Basic is ranked 62nd. The most important reason people chose APL is:
No complicated loop processing to apply a function to a array of arrays. Functions are defined in a way that they will typically operate the same way on any number of array dimensions. This, along with the clear syntax, leads to very compact code that can be comprehended in a single line, rather than spread out over many pages.

Pro High-level

Pro Iverson award in 2016
Pro Very concise
Pro Clear syntax
There is no operator precedence to memorize, as everything is evaluated right-to-left. E.g., in APL 3*10+3 = 39. You do have to type in some otherwise unusual characters, such as ↓ and ∊, but those are easy enough to pick up -- and they have the advantage of being easily remembered once understood, as they often have some connection to common mathematical symbols.
Pro Terse
You can seriously implement Conway's Game of Life in one line. There's a reason we do algebra with symbols instead of story problems. APL is good as a language of thought, since you can hold entire algorithms in your head at once.
Pro Very simple and efficient language (in terms of number of lines of code)
Pro Easy to learn
Pro Capable language
Compiling to the same intermediate language as C# and compiling against the same .NET libraries, the differences between C# and VB are largely syntactic. Most VB features even have a 1:1 correspondence with C#.
Pro Huge community
Being Microsoft's introductory language, visual basic has a strong and large community.
Pro English-like syntax
Pro Flexible, won't get in the way of a beginner
A beginner developer can worry about the code logic first, and then learn the language. Visual Basic lets you do basically anything if you really want, while still having the power to be a fully statically-typed and object oriented.
Pro Sibling to C#
If you don't want to start with C# because of its high learning floor, you can start with VB. It is dead easy to switch between the two.
Pro Easy to deal with Win32API
Using platform invoke, it's very easy to use the win32 api in vb.net. Neat and clean syntax. Not a mess like c# (meaning those "{}"s).
Cons
Con Hieroglyphics
APL symbols are only used by APL. You have to learn how to type them and how to read them. It doesn't work well with standard text editors , version control systems, search engines, or web forums. This makes it difficult for a beginner to find help.
Con Does not prepare you for most of the practical programming languages of today
While APL does have a strong use in certain areas (mostly mathematically intensive applications), it is a Domain-Specific language. That along with the fact that its syntax is not similar to C-like or other common syntax forms means that learning APL and expecting it to help you with learning other languages is like learning Calculus and expecting it to make English easier.
Con Write-only language
Maybe you can learn to read it with experience. And an interpreter. Reading APL is like reading a college math book. You might have to study a single line for fifteen minutes to understand what it's doing. And that's if you're an expert at APL. This also applies if you wrote it yourself more than a month ago. hopefully you have comments.
Con Flawless diamond
You can't extend the language itself. (J does this better.) Of course, what's built in is quite powerful.
Con Almost as bad as Python, but less used
Con Bad reputation
Being a visual basic programmer, you're unlikely to be taken seriously by other programmers. According to the 2015 Stack Overflow survey, it was voted the second most dreaded language among developers.
