04. For-In Loops

INSTRUCTOR NOTE:

Clarification

Use forEach or for to iterate over arrays like:

countries = ['Argentina', 'China', 'England'];

Use for-in to loop over objects like

countries = {'country1':'Argentina', 'country2':'China','country3':'England'};

being careful to wrap the content of the for-in in a conditional statement that tests if the key is part of the object:

myObj = {'country1':'Germany', 'country2':'Argentina'};
for (key in myObj){
    if (myObj.hasOwnProperty(key)) {
        console.log(myObj[key]);
    }
}</pre>

For more information, please refer to the loop section of the Udacity Front End Style Guide.

:last
The :last jQuery selector returns the final element in a list that matches whatever precedes it. 

So for work-entry:last, if there are 3 work-entry elements, it will only return the 3rd one.

If you're interested, you can read more about jQuery's :last selector here.



For this quiz you'll work with the index.htmland js/resumeBuilder.js files from the résumé project's Github repository you downloaded earlier in this lesson. Edit js/resumeBuilder.js in your text editor, and view the results by opening index.html in the browser of your choice. Note that the HTML needed is stored in js/helper.js variables.
