im·mu·ta·ble i(m)ˈmyo͞odəb(ə)l/ adjective - unchanging over time or unable to be changed.

Mutating data is the source of never ending headaches in software systems, and JavaScript code is no exception. Immutable data structures, pure functions, uni-directional data flow... you've probably been hearing these terms.

Immutable.js provides us the data structures and utilities that we need to start introducing this powerful concept of immutability into our applications.

    What would make this course a 7 for you?

    The last video example (JS Bin) doesn't match with its discussion and examples.

    Avoid having extra/separate functions if it will only be used once as it would be difficult to keep track on the examples provided except for the 'reduce' lesson part as it was great separating its transform functions.

    All in all, it was great. Thank you :)

    What did you like about this course?

    Great stuff. I really like your approach to have tests defined and then make them passing. I have not seen such approach with any other course. I would like to see all courses made this way. :)
