typescript - Skip type check on unused parameters -

when compile typescript project, i'm using noimplicitany option won't forget specify types on variables , arguments.

however have arguments don't use. example:

jquery.ajaxtransport("+*", function (options: jqueryajaxsettings) {   return {     abort: function (_, callback: jquerycallback) {  

i not interested in first argument of abort function, ignore naming _.

is proper way in typescript? couldn't find in guide. suspect isn't proper way, because can name 1 argument _.

typescript raises following error:

error ts7006: parameter '_' implicitly has 'any' type.

i type _:any seems bit overkill argument don't use.

there no way skip unwanted parameters in javascript or typescript.
