at < String < JavaScript

The at() of a String takes an integer and returns the character (UTF-16 code unit) located at the specified zero-based offset/index. Negative integers count back from the last string character.

    
    const sentence = 'The quick brown fox jumps over the lazy dog.';

    const sentenceAtFive = sentence.at(5);

    console.log(sentenceAtFive);
    // "u"
