JavaScript is Case Sensitive
A function named "myfunction" is not the same as "myFunction".
Therefore watch your capitalization when you create or call
variables, objects and functions.
Symbols
Open symbols, like ( { [ " ', must have a matching closing
symbols, like ' " ] } ).
White Space
JavaScript ignores extra spaces. You can add white space to your
script to make it more readable. These two lines means exactly
the same:
name="Hege"
name = "Hege"
Break up a Code line
You can break up a code line with the backslash. The example
below will be displayed properly:
document.write \
("Hello World!")
You can insert special characters (like " ' ; &) with the
backslash:
document.write ("Me \& you sings \"Happy Birthday\".")
The example above will produce this output:
Me & you sings "Happy Birthday".
Comments
You can turn a line into a comment, like this
// This is a comment
You can also create a comment block, like this:
/* This is a comment block. It contains several lines*/
