Build times are much faster. I’m a ‘code it, save it, check it’ kind of programmer, programming features bit by bit rather than all at once. Meteor rebuilds (on the server especially) take a really long time. On Elixir (with Webpack, in my case), it’s virtually instantaneous, meaning less time to get distracted.
Pattern matching has saved my bacon on more than one occasion already. Writing GraphQL queries which have different arguments with the premier GraphQL library (http://graphql-elixir.org/) is a cinch. I’m sure I’ll just keep finding uses for that language feature.
More to come
