categories of programming languages

machine language

designed specifically for computer hardware. The CPU directly affects such language

assembly language

simplifying and making readable machine code. uses symbolic names instead of binary to represent instruction

mnemonics

runs via interpreter

easier than system language

great for quick task, automation and integration between system

key traits of scripting language

python

java

typescript

javascript

c++

common programming languages

python

used for building a wide range of applications from web development to artificial intelligence

java

follows the principle of “write once, run anywhere, ” meaning code compiled in Java can run on any device

java virtual machine

JVM

typescript

open source programming language developed by microsoft

javascript

lightweight cross-platform object-object oriented scripting language

c++
