What are the main differences between Python and JavaScript programming languages?

Python and JavaScript are both popular programming languages , but they have some key differences in terms of their syntax , features , and use cases . Here are some of the main differences between Python and JavaScript : \n \n 1 . Syntax : Python has a simple and easy - to - read syntax , with a focus on read ability and ind entation to indicate code blocks . JavaScript , on the other hand , has a more complex syntax , with a mix of cur ly bra ces , sem icol ons , and other symbols . \n 2 . Object - orient ed programming : Python is an object - orient ed programming language , which means it emphas izes the creation of objects and classes . JavaScript also supports object - orient ed programming , but it is not as central to the language as it is in Python . \n 3 . Data types : Python has a few built - in data types , including integers , flo ats , strings , and bo ole ans . JavaScript has a wider range of built - in data types , including numbers , strings , bo ole ans , objects , arrays , and more . \n 4 . Function s : Both languages support functions , but they are used differently in each language . In Python , functions are first - class citizens , which means they can be assigned to variables and returned as values from other functions . In JavaScript , functions are used extens ively for event handling and for creating re usable code . \n 5 . Web development : JavaScript is the primary language for web development , while Python is more commonly used for back - end web development and for building desktop applications . \n 6 . L ibr aries and frameworks : Python has a large number of libraries and frameworks available for a wide range of tasks , including machine learning , data analysis , and web development . JavaScript also has a large number of libraries and frameworks , but they are more focused on front - end web development . \n \n Over all , both Python and JavaScript are powerful programming languages with their own strength s and weak ness es . The choice of which language to use will depend on the specific task at hand and the developer ' s personal prefer ences . </s>
