- HTML: With HTML5 more of an evolution than a revolution from its predecessor, you can feel confident that someone skilled in the original can learn the “5.”
- CSS (including CSS preprocessors like SASS and LESS): This establishes the look and formatting for web pages. Like HTML5, this can be picked up easily with a few online courses. You may also see CSS3, which is the newer generation of CSS and contains cool interactions like animations and rendering.
- C++: Objective-C is the primary language used to build iOS applications. Objective-C uses a similar syntax and structure as C++ applications, so if a tech pro knows C or C++, it will be easy for them to grasp Objective-C.
- Android SDK: Java experience is fairly common in the development world. But, Android app development is not. With that in mind, a Java developer will be able to learn the ins and outs of the Android SDK (Software Development Kit) in a matter of months. Developers who also have embedded programming in other areas, even an iOS experience, should be able to learn Android development.
