# Welcome to Juno!

# If you're new to Julia, you can find a tutorial here:
# http://link to a nice tutorial.com

# Generally, if there's something you'd like to do but don't know how, try
# searching in the command bar (Ctrl + Space) - almost all possible commands 
# can be found there.

# To evaluate a line of code, press C + Enter¹. The result will be displayed
# inline, while using e.g. print will display the output in the console
# (View -> Console).

1 + 1
println("Hello World!")

# If the cursor is inside a block of code, pressing C + Enter will evaluate
# the entire block and display the last result inline.

begin
    println(cos(π))
    t = cos(π)
end

for i = 1:10
    i^2
end

function square(x)
    return x*x
end

# You can have a look at the variables and functions defined in the
# current file by opening the object browser (View -> Object browser).

# The documentation for functions is available via Ctrl + D and all methods
# of a function will be listed with Ctrl + M.

sin(4)

# Note, however, that all methods will be displayed, not the curently used
# one (this is because of Julia's dynamic nature: Juno can't generally
# determine the type of the input arguments).

# If errors are encountered during the evaluation of some Julia code,
# Juno will display the backtrace and provide a link to the faulty
# line of code.

function iError(x)
    [x x]*[x x]
end

iError(1)

# This error message can be removed by either fixing the problem and 
# re-evaluating, double-clicking it or right clicking and selecting
# 'Remove result'.
