The development environment is VS Code and Ubuntu via WSL.\r\n\r\n### Day 1\r\nJulia provides no extra benefit.\r\n\r\n### Day 2\r\nAgain no special benefit of Julia, but I'm thankful that Julia has regex support, and I like the array\r\nfunctions with predicates and the fact that comparisons can be chained.\r\n\r\n### Day 3\r\nModular arithmetic is a pain when dealing with array indexes because of the 1-based indexing.\r\n\r\n### Day 4\r\nRegex support is key.\r\n\r\n### Day 5\r\nBasic binary conversion.\r\n\r\n### Day 6\r\nSupport of sets in Julia helped.\r\n\r\n### Day 7\r\nHad problems with mutability and recursion in julia. I had problems with a complicated regex and a clunky IDE.\r\n\r\n### Day 8\r\nProbably could have optimized, but there is no need. Waiting to get to some meaty vector reduction puzzles that can show the power of julia.\r\n\r\n### Day 9\r\nOne annoyance with julia is that there are **many** library names in the global namespace that sometimes (for reasons that are not clear to me) will collide with local names.\r\n\r\n### Day 10\r\nFinally, a puzzle with a little bit of a challenge. Is there a way to create a Dict element initialized to 0 simply by referencing it? I could avoid having to use haskey() to know if I need to create the entry first.","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjambolo%2Fadvent-of-code-2020","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fjambolo%2Fadvent-of-code-2020","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fjambolo%2Fadvent-of-code-2020/lists"}
