Language's own native data-structures are generally much more capable and vast. 99%+ developers use only a very limited set of those capabilities. This approach packages those most used ones into a nice, consistent DSL.
It's similar in effect to what busybox does to shell utilities, though the motives are different.
agreed but depends on then language. for instance, the .NET equivalent (MemoryCache) is pretty poor.
Doesn’t depend on the language? Actually I am thinking of the standard library… Python’s in kinda huge and some are hard (for me) to grasp. Golangs seem pretty simple.
