Case in point, I'll be using the project on Azure CosmoDB but I cannot send bytecode as it's not yet supported, they're working on it. So I don't want to have to write all my queries as strings and then have to go back at a later date and convert to glv steps. I'd rather use the glv steps and go back later and implement terminal commands. This might just be my own personal preferences, but I'm sure others would appreciate that flexibility? This is how it would be used: ```javascript const g = new graph.Graph().traversal(); g.V().order().by('age', t.order.decr); const script = new Translator('g').translate(g.getBytecode()); ``` That script could then be submitted via the client. ---
