I think that Javascript is much easier to program in compared to other programming languages that I’ve learned. For example, you don’t need to define variable type by int or float. In regards to ES6, I learned about the two new variable type let and const. let comes in handy because it’s a block scope variable and const is useful because you don’t have to worry about changing the variable if you do end up writing a modification to that variable in your code. From a software engingeering perspective Javascript is a good programming language to learn because of its relative ease to learn, it’s robust usage, and frameworks supporting the language allows Javascript to work in both front-end and back-end.
Athlectic software engineering is fun, but it isn’t useful for learning because it puts stress on the student to complete the WOD for a grade when WODs should be there for the student to learn how to program better. A better style of learning would be to complete WODs without time limits and go over an efficient solution to the code that you worked on.
