title: How to force all variables in Typescript to have a type declared
body: <p>I understand that when you declare a variable in Typescript, you can choose whether or not to specify a type for the variable.  If no type is specified, the default "any" type is used.  Is there a way to force all variables to have a type declared, even if it may be "any".  As in, I want a compiler error when a type isn't specified.  This is so that programmers would be forced to give everything a type and prevent cases where variables are accidentally left as "any".</p>
