Programming languages are formal languages for writing instructions that computers follow. They let people build software, automate tasks, and control devices. Examples include Python, Java, and C, each with different strengths.
Some programming languages manage to absorb change, but withstand progress. Alan Perlis
In English every word can be verbed. Would that it were so in our programming languages. Alan Perlis
The precision provided (or enforced) by programming languages and their execution can identify lacunas, ambiguities, and other areas of potential confusion in conventional [mathematical] notation. Kenneth E. Iverson
Most programming languages are decidedly inferior to mathematical notation and are little used as tools of thought in ways that would be considered significant by, say, an applied mathematician. Kenneth E. Iverson
Overemphasis of efficiency leads to an unfortunate circularity in design: for reasons of efficiency early programming languages reflected the characteristics of the early computers, and each generation of computers reflects the needs of the programming languages of the preceding generation. Kenneth E. Iverson
The properties of executability and universality associated with programming languages can be combined, in a single language, with the well-known properties of mathematical notation which make it such an effective tool of thought. Kenneth E. Iverson
