Of course when you first start expect to enter the field at around 43k depending upon location and portfolio.

NOTES:

A lead/senior front-end developer/engineer can potentially live wherever they want (i.e., work remotely) and make over $150k a year (visit angel.co, sign-up, review front-end jobs over $150k or examine the salary ranges on Stack Overflow Jobs).
