GNU Bash vs Objective-C: What are the differences?
GNU Bash: Functional improvements over sh for both programming and interactive use. The Bourne Again SHell is an sh-compatible shell that incorporates useful features from the Korn shell (ksh) and C shell (csh). It is intended to conform to the IEEE POSIX P1003.2/ISO 9945.2 Shell and Tools standard; Objective-C: The primary programming language you use when writing software for OS X and iOS. Objective-C is a superset of the C programming language and provides object-oriented capabilities and a dynamic runtime. Objective-C inherits the syntax, primitive types, and flow control statements of C and adds syntax for defining classes and methods. It also adds language-level support for object graph management and object literals while providing dynamic typing and binding, deferring many responsibilities until runtime.
GNU Bash belongs to "Shells" category of the tech stack, while Objective-C can be primarily classified under "Languages".
Uber Technologies, Instagram, and Pinterest are some of the popular companies that use Objective-C, whereas GNU Bash is used by AgFlow, Clippings, and Lithium Technologies. Objective-C has a broader approval, being mentioned in 851 company stacks & 363 developers stacks; compared to GNU Bash, which is listed in 40 company stacks and 73 developer stacks.
