is there anyway to check if a string could be used a variable name. So
return false if the first character isn't a letter or if it contains
spaces etc.
I started writing a function that would do a load of tests because I
couldn't see any easier way of doing it:

function is_valid_handle($str) {

I am writing some code to search for strings that contain every letter

regular expression – so I need something like match true if...

Hi,
I have a string like,
s1 = '12e3'
s2 = 'junk'
Now before converting these values to float, I want to check if they
are valid numbers.
s1.isdigit returns False.

the subject pretty much says it all.
if I check a string for for a substring, and this substring isn't found,
should't the .find method return 0 rather than -1?
this breaks the
if check.find('something'):
do(somethingElse)
idiom, which is a bit of a pity I think.

Does anyone know why the string contains function always returns true
if the token is an empty string? I expected it to return false.
"AnyOldText".Contains("")
or
"AnyOldText".Contains(String.Empty)

Dear newsgroup.
I want to write a template function which accepts either integer or
floating point numbers.
If a certain result is not a whole number and if the template
parameter is an integer, it should return false, but it should work
normally if the parameter is a float.
To illustrate this, I attached a minimal example.

function isNumber(n) {
return !isNaN(parseFloat(n)) && isFinite(n);
}
as the best solution, is it? Plus why both !isNAN and isFinite() are used together, which weaknesses each other covers?
