Solutions
Solution 1 (Click to Show/Hide)
Add the key attribute to the <li> and give it a unique value.
Using the array element as the key:
const renderFrameworks = frontEndFrameworks.map((item) =>
<li key={item}>{item}</li>
);
Using the array index as the key (should be avoided):
const renderFrameworks = frontEndFrameworks.map((item, index) =>
<li key={index}>{item}</li>
);
