Javascript as it was

“

Was invented by Brendan Eich

in 1995

“

Was written in

10

days

“Sometimes is a bit immature...

var x = ['10', '10', '10'];

var y = x.map(parseInt)

console.log(y) ////[10, Nan, 2]

“Sometimes is a bit immature...

console.log(NaN === NaN)

//false

“Sometimes is a bit immature...

console.log(typeof [] === typeof {})

// true

“But it is certainly funny!

console.log(Array(16).join('a' -1) + " Batman!")
