Using Julia inside Jupyter Notebook isn't difficult. I will assume you have installed Julia.
To use Julia in Jupyter notebook, first launch Julia's REPL and add the IJulia package.
using Pkg
Pkg.add("IJulia")Once the IJulia package is installed, launch notebook from inside Julia's REPL.
using IJulia
notebook()Notebook will launch, then select "Julia" as the kernel.
You can then write cells as you normally would inside Jupyter Notebook.
