Julia 1.0 Programming Complete Reference Guide

Manipulating strings

Strings can be treated as a list of characters, so we can index into them—that is, access the character at a certain position in the word:

julia> str = "Nice to see you" 
julia> str[1]

The first character of the string Nice to see you is N.

Indexing in Julia is 1-based, which means that the first element of a list is found at index 1. This can be surprising if you've programmed before, given that most programming languages use 0-based indexing. However, I assure you that 1-based indexing makes for a very pleasant and straightforward coding experience.

Julia has support for arrays with arbitrary indices, allowing, for example, to start numbering at 0. However, arbitrary ...
