- Write a function that converts a hexadecimal color, for example blue (
#0000FF), into its RGB representation,rgb(0, 0, 255). Name your functiongetRGB()and test it with the following code (hint: treat the string as an array of characters):> var a = getRGB("#00FF00"); > a; "rgb(0, 255, 0)" - What do each of these following lines print in the console?
> parseInt(1e1); > parseInt('1e1'), > parseFloat('1e1'), > isFinite(0/10); > isFinite(20/0); > isNaN(parseInt(NaN)); - What does this following code alert?
var a = 1; function f() { function n() { alert(a); } var a = 2; n(); } f(); - All these following examples alert
"Boo!". Can you explain why?- Example 1:
var f = alert; eval('f("Boo!")'), - Example 2:
var e; var f = alert; eval('e=f')('Boo!'), - Example 3:
(function(){ return alert;} )()('Boo!'),
- Example 1:
