Javascript: the good parts - CTO Yahoo

The worlds most misunderstood programming language

complaints:

"JS is not a language that I know"
"The browser programming experience is awful"
"It's not fast enough"
"the language is just a pile of mistakes"

Under the surface, JS actually has good parts

Java as a client language was a disaster but JS is still being used

Bad Parts:

• global variables
• + adds and concatenates
• Semicolon insertion
• typeof
• with and eval
• phony arrays
• == and !=
• false, null, undefined, NaN
