Count strings in objects

[hellocan]

Create a function strCount (takes an object as argument) that will count all string values inside an object. For example:
strCount({
first: "1",
second: "2",
third: false,
fourth: ["anytime",2,3,4],
fifth: null
})
//returns 3

Your Test Cases:
Test.assertEquals(strCount({
first: "1",
second: "2",
third: false,
fourth: ["anytime",2,3,4],
fifth: null,
sixth: undefined,
seventh:{}
}),3,"Did not count the correct number of strings. Check counting inside nested objects.");
