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 . Here are some of the main differences between Python and JavaScript : \n \n 1 . Sy ntax : Python is known for its clean and simple syntax , while JavaScript is more complex and has more cur ly br aces . \n \n 2 . Object - O ri ented vs . Pro totype - Based : Python is an object - oriented language , which means that it uses classes to define objects and their behavior . JavaScript , on the other hand , is a prototype - based language , which means that it uses pro tot ypes to define objects and their behavior . \n \n 3 . Typ ing : Python is a dynam ically typed language , which means that you don ' t need to declare the data type of a variable . JavaScript , on the other hand , is a lo os ely typed language , which means that you can assign different data types to a variable , but it will be automatically as the data type of the last assignment . \n \n 4 . Execut ion : JavaScript is primarily used for client - side script ing , which means that it runs on the user ' s browser . Python , on the other hand , is primarily used for server - side script ing , which means that it runs on the server . \n \n 5 . L ibraries and Frame works : Python has a large number of libraries and framework s that can be used for web development , data analysis , machine learning , and more . JavaScript also has a large number of libraries and framework s , but they are primarily used for front - end development , such as React , Ang ular , and V ue . js . \n \n Over all , Python and JavaScript are both powerful programming languages , but they have different strengths and use cases . Python is a good choice for server - side script ing , data analysis , and machine learning , while JavaScript is a good choice for front - end development and client - side script ing . </s>
