As a front-end development engineer, you definitely need to combine some tools to assist development. At present, Dreamweaver, Sublime Text and HBuilder are commonly used.

After you become more capable, tools may not help you much because of their own limitations, so you will start to contact more frameworks, besides Angular, React and Vue, as well as Bootstrap. Fbootstrapp, BootMetro, Gumby, IVORY, Kube, etc. It's all about getting in touch slowly

The front-end learning is wide and the knowledge is chaotic. Of course, no one can succeed in one step. Take your time, learn slowly, and you will succeed.
