how to retrieve key and value from object search?

I want to find a page url searching by an input. I have an object that contains keywords and urls. Then when press enter it will do a check, if the keywords are the same or exist, it will display the url, if not it will display not found.

So for example in the input I type “home”, when I enter it will display the url “/homepage” because the keywords are exist, if I type “contact” it will show not found because the keywords doesn’t exist.

I’ve made the code like below but why the map doesn’t work? can anyone help me?

$(document).ready(function(){
  $("#searchKeywords").on("keypress", function(e){
    if(e.which == 13){     
      const pageKeywords = {
        "home" : "/homepage",
        "about" : "/about-us"
      }

      pageKeywords.map((key,value) => {
        console.log(key)

        if($(this).val() == key){
          console.log(value)
        }else{
          console.log('not found')
        }
      })
    }
  });
})
