I have a string that looks like this:
2014-02-23
and I want to add quotes to either end.
"2014-02-23"
What is the best way to do this?
The simplest :
'"'+s+'"'
The jsonest (only if your string doesn't contain quotes) :
JSON.stringify(s)
The regexest :
s.replace(/^|$/g,'"')
The best ? Choose your own.

I tried changing the string, and tried repeating everything over and over. Nothing seems to work.
Edit: Thanks for the replies, it is working now.
It says that you create a new variable let temperature but you are not using it anywhere in your code
If you want to use it in the alert you should use backticks `` for s tring interpolation instead of single quotes ''

I want to create a double headed arrow/html element in my web page with some text in it. Basically an arrow like in shapes in MS Word.
Also, I want it to be clickable so that I can trigger any event on the click.
How can I accomplish this?
Some double-headed arrow characters exist in UTF-8 if you don't want to draw it yourself in CSS :
U+2194 ↔
U+2195 ↕
U+21D4 ⇔
U+21D5 ⇕
This page has a lot of them if you need more.

where file name could contain any digits before the "-123x123", numbers in the "-123x123" could be any numeric values.
The answer is:
-\d+x\d+(?=\.jpg)
\d means "digit"
(?=....) means "followed by"

I'm trying to figure out the best way to replace a string between 2 other strings. I believe regex is necessary for this.
Input string:
"http://domainabc.com/dir1/dir2"
Output string:
"http://domainxyz.com/dir1/dir2"
Only the domain will change - not the subdirectories.
Probably you're looking to change current domain name without bothering what the domain is. Try this code:
var s = "http://domainabc.com/dir1/dir2";
repl = s.replace(/\b(https?:\/\/)[^/]+(.+)$/, "$1domainxyz.com$2");
//=> http://domainxyz.com/dir1/dir2
