# Introduction _*note: this page requires a font which can show apl symbols.*_ APL and J are very different from other (more conventional) programming languages, and therefore they require a little bit of introduction. Their syntax is very dense, and can be hard to read at times for a person not very familiar with it. # To be written at some point +/⍳200 is the sum of the first 200 natural numbers in APL, and in J it would be +/i.200 nice.
