Indexing arrays

Slicing arrays

Working with arrays

Modifying arrays

Fibonacci sequence

Appending arrays

Operating on arrays

Finding the array length

Array operating fluency

Operating on body temperatures

 Data structures

Learn to write code that can make its own decisions using conditional expressions and write functions so you can reuse your code. Plus, learn Julia's powerful function features like broadcasting and multiple dispatch.

Conditionals

Comparisons

Check input data type

If-else practice
