I find Typescript catches all sorts of typos that get missed in pure JS because I don't have 100% code coverage tests. Sure a JSLinter might catch some of those, but it won't find mis-spelled method names. Other benefits include not having to remember the 'interesting' rules around 'this' in pure JS (though that occassionally slips through in libraries that use it). Having saner (to my eyes) syntax for modules and encapsulation. And having intellisense support in Visual Studio reduces the effort of writing the code.
