// Correct: returns '1'
    'Résumé'.localeCompare('RESUME', undefined, {sensitivity: 'accent'})

localeCompare() returns 0 if the strings are equal and -1/+1 if they're different. Since this section is about comparing two strings that only differ in case and accents, I would expect to see a method I could use that would consider the strings to be equal. Instead, this example just shows two ways to compare strings (=== and localeCompare) that both consider the strings to be different.
