Manipulating an array

Take the following array:

const theList = ['Laurence', 'Svekis', true, 35, null, undefined, {test: 'one', score: 55}, ['one', 'two']];

Manipulate your array using various methods, such as pop(), push(), shift(), and unshift(), and transform it into the following:

["FIRST", "Svekis", "MIDDLE", "hello World", "LAST"]

You can take the following steps, or adopt your own approach:

• Remove the first item and the last item.

• Assign hello World to the fourth item value.
