Difference between :remote => true and remote: true

Question

What's the difference between these two options? They seem to do the same thing.

Both are the same the difference is Hash syntax for 1.9+ Ruby versions and 1.8- Ruby versions:

# Ruby 1.8 Syntax
{:this => 'syntax', 'is' => 'fun'}
# Ruby 1.9 syntax
{this: 'syntax', more: 'fun'}

As written in the referred post: It just looks nicer--it's syntactic sugar; it ends up being the same thing.

Please elaborate that your second example is in fact broken. – lorefnon Apr 29 '15 at 19:42

What's broken? If the compiler is complaining, could that mean you're running on Ruby 1.8? – Katana314 Apr 29 '15 at 19:44
thanks @lorefnon fixed, Katana314 there was an extra quote – mohamed-ibrahim Apr 29 '15 at 19:45

There is no difference. The first is the older syntax for defining a key value pair for hashes. The second was introduced with Ruby 1.9 (I think).

If you're using a version of Ruby pre 1.9 you will have to use the first syntax, otherwise you should use the second syntax.

There is a difference. There are no "older" and "newer" syntaxes, the JavaScript-style syntax only applies to *some* symbols in Hash literals, if your keys are not a limited set of symbols then you need to use the hashrocket. – mu is too short Apr 29 '15 at 19:57
