Julia Keywords

Keywords in Julia are reserved words that have a predefined meaning to the compiler. They are used for some internal processes by the compiler. Keywords can't be used as a variable name. Doing the same will result in a compile-time error. Example:

Python3 1==

# Julia program to illustrate
# the use of keywords

# Using 'for' keyword 
for i in 1:10
    
    # Using if keyword
    if i % 2 == 0
        println(i, " is even")
    
    # Using else keyword
    else
        println(i, " is odd")
    
    # Using end keyword
    end
end

Output

1 is odd
2 is even
3 is odd
4 is even
5 is odd
6 is even
7 is odd
8 is even
9 is odd
10 is even

If we use a keyword as a variable name, the compiler will generate an error: Keywords-in-Julia-01
