I like Sublime Text Editor (this is what I'm currently using now for web development, it's quite fast and convenient editor without too much functionality, you can download a lot of free extensions to extend functionality so it's even more powerful), Adobe Brackets, Atom.io these are also quite new and quite lightweight in size. And of course you can find even more using any search engine like Google, Yahoo or Bing.
It takes time to get really comfortable with IDEs but it's worth it. Although many people will recommend you IDEs, but for me I find that it's faster and easier to use just lightweight code editors especially when I'm learning something new or when building small to medium projects. Just try a few code editors and IDEs of course you will lose your precious time but in the future it pays off and you will definitely end up more productive.
