Comparison of npm scripts vs Gulp

npm scripts

Pros

• npm scripts are low-level and leverage the actual library you want to use (example: "lint": "eslint ./")
• package.json is a central place to see what scripts are available (also npm run will list all scripts)
• When things get too complicated you can always defer to another file (example: "complex-script": "babel-node tools/complex-script.js")
• npm scripts are more powerful than one might first think (pre/post hooks, passing arguments, config variables, chaining, piping, etc...)
