JavaScript was created in 1995 by Brendan Eich at Netscape. It has gone through many versions and specifications over the years as its usage on the modern web has increased. JavaScript now powers much of what happens on the client-side of websites and web applications. While JavaScript was initially created in only 10 days, it has evolved significantly and become a complex language that continues to change and expand its capabilities. Learning JavaScript requires understanding its history and changes over time as well as developing a broad set of skills in front-end web development.
