Partly to realize that and partly to attenuate obscure code like a supply of mistakes, The foundations also emphasize simplicity plus the hiding of needed complexity behind very well-specified interfaces.

Efficiency: A change compares against constants and is generally better optimized than a series of assessments in an if-then-else chain.

Use algorithms which can be designed for parallelism, not algorithms with unneeded dependency on linear analysis

(difficult) Flag loop variables declared ahead of the loop and utilised after the loop for an unrelated goal.

By stating the intent in source, implementers and equipment can offer far better diagnostics, which include acquiring some classes of faults by way of static Examination, and carry out optimizations, such as taking away branches and null assessments.
