INTRODUCTION

JavaScript is one of the three primary languages required to create and develop content for the World Wide Web. It is a core competency that all web developers should know and is vital to modern interactive websites. Without JavaScript and its nearly universal support built into most web browsers, websites would not be able to perform event-driven activities so common in modern website design.

SALARY RANGE

According to ZipRecruiter, the salary for a JavaScript developer in the United States ranges from about $37,500/year to around $178,000/year. The median salary in that range is $117,000/year.

DETERMINING FACTORS, DESIRABLE PERSONALITY TRAITS AND SKILLSETS

Like most programmers, coders and developers, the most effective JavaScript developers should have specific personality traits. Look for candidates that are intellectual, introspective, inquisitive, curious, methodical, rational, analytical and logical. A quality JavaScript developer should be able to work in a fast-paced environment and implement complex design specifications.
