What Are Python AI Libraries?
Python AI libraries are pre-written collections of code that provide standardized functions and tools for developing AI and ML models.
These libraries save developers significant time and effort by offering reusable code that handles various tasks related to data processing, model training, and evaluation. Essentially, they allow developers to focus on designing and refining models rather than writing low-level code.
Similar to the AI-enabled python tech stack, even JavaScript has an ample amount of frameworks compatible to build machine learning applications.
Each of these two subsets of Traditionally used programming languages brings unique and resourceful features to the table, in such cases you can always compare Python & JavaScript to decide which one's better for your project.
