Question

What does the \":\" mean in the 3-6th lines below?

function displayError(error) {
    var errorTypes = {
        0: \"Unknown error\",
        1: \"Permissi         


        

Answer 1

That's how you define key value pairs in an object. So errorTypes.2 would return the string "Position is not available".
