In this exercise, create a tag function named “upper” which transforms the variable values in the template string to uppercase. The code for this exercise is in the ex4.js file.
(cool music)…- Let's go ahead and open up exercise four.…Exercise four gives you this silly example,…and you need to write a tag function…that uppercases only the values, not the strings.…So, you're gonna need to modify line eight…to use the tag function,…put in your interpolated expressions appropriately…in those places where the underscores are,…and then, write your upper function to do the looping…just exactly the same way I just showed you.…
