trying to create a function that results to this
describe('introductionWithLanguageOptional(name, language)', function() {
it('takes in two arguments, a name and a language, and language defaults to JavaScript', function() {
expect(introductionWithLanguageOptional("Susie")).toEqual("Hi, my name is Susie and I am learning to program in JavaScript.");
})
})
function introductionWithLanguageOptional(name, language = "JavaScript") {
return `Hi, my name is ${name} and I am learning to program in ${language}.`
}
