Scala from a developer's perspective
Posted: Mon Jan 27, 2025 4:36 am
Scala was a better language than Java right from the start. Functional programmers were happy about the support for their paradigm anyway. But even those who weren't interested in Scala's functional concepts benefited from the more compact syntax, local type inference and unified generics, for example.
But a language also requires tooling and an morocco gambling data ecosystem, and for a long time there were a few shortcomings: the compiler was comparatively slow and the IDE support was not as mature as for Java.
A major problem with Scala 2 was that version jumps within the major version (for example from 2.11 to 2.12) generally involved changes to the ABI, i.e. the conventions of the generated bytecodes: Libraries compiled with Scala 2.11 could not be used in Scala 2.12 projects. To release a library, it was not enough for the authors to provide a single JAR file - they had to do this for every supported version of the Scala compiler. Anyone who wanted to update a project to a newer Scala version therefore needed corresponding versions of all libraries. If one was missing - tough luck.
In the meantime, however, the situation has stabilized: In general, all Scala 3 libraries and Scala 2.13 libraries can be used in projects with the current Scala 3 version. The situation is likely to remain positive because the formalized governance structure for the Scala project [4] established since 2022 regulates, among other things, predictable release cycles and version compatibility.
