Challenge: Get Elements Using Attributes

Problem statement #

Your task is to convert the input entered for First name to Upper Case.

Note: Do not modify the input entered for the Last name. It should stay as it is.

You need to do this by implementing the functions getElementByAttribute (that accesses an element of the DOM using its attribute) and the function lowerupper.

Take a look at the HTML code first before writing the JavaScript code.

Input #

First name and Last name

Output #

The first name in capital letters and the lower name as it is

Sample input #

"First name": "Bob"
"Last name" : "Builder"

Sample output #

"BOB"
"Builder"
