Why are there so many programming languages? -


you may think question stupid or new student, think when learn 1 language (ex. java), tend forget 1 learned before (ex c)... or mixed-up syntax.... why not merge 1 students don't need learn many languages... kill useless programming languages... why not create standard sql????

different languages address or embrace:

  • different needs (performance in specific areas, reliability, ease of expressing niche programs etc)
  • different platforms
  • difference models (functional, oo etc)
  • different histories

there many programming languages "general purpose" , others specific particular situation... within "general purpose" programming languages, no language stands out being ready replace others.

note example of sql, db vendors have own extensions sql, required take database beyond "here's query, give me table of results".
