What is the difference between Dependencies and DevDependencies?

Question

Building projects

I'm a little confused about the installation. For example sass and pug we put how?

npm gulp-sass --save-dev
npm install gulp-pug --save-dev

Everything that is simple with --save is Dependencies - it will go into production, everything that with --save-dev is DevDependencies will not go into production? So if I install Bower myself, then it must be installed with --save-dev. we don’t need it on the sale, and then when I use Bower to install jquery, I just need to install it with --save. jquery should go into production?
