According to W3Tech, this link, this link, this link, and many other sources, jQuery is really becoming what IE experienced in the world of web browsers (gaining more than 80% of the market for a period).
I don't have the knowledge of any other JavaScript library like MooTools, YUI, etc. because when I started web development, jQuery was already ahead and I chose it.
Are other libraries really that awful, or do they lack something jQuery exclusively has? What is the reason(s) behind this huge market share?
"what IE experienced in the world of web browsers"
What do you mean?
