How can HTML entities improve website accessibility?

Displaying Code Snippets

To ensure code snippets are rendered accurately and understood by assistive technologies, special characters must be escaped.

Problematic Code (Unescaped)

    const greeting = "Hello & World!";
    if (x < y) {
        console.log("x is less than y");
    }
    

Accessible Code (Escaped using html-entity)

The following code uses HTML entities to correctly display special characters:

    // Assuming you're using a JavaScript library or backend to escape:
    // const escapedGreeting = htmlEntity.encode('const greeting = "Hello & World!";');
    // const escapedCondition = htmlEntity.encode('if (x < y) {');
    // const escapedLog = htmlEntity.encode('    console.log("x is less than y");');

    // For demonstration, manually escaped:
    const greeting = "Hello & World!"; // & represents '&'
    if (x < y) { // < represents '<'
        console.log("x is less than y");
    }
    

Explanation for Assistive Technologies: When a screen reader encounters the above, it will correctly interpret "Hello & World!" as "Hello and World!" and "x < y" as "x less than y", preserving the code's intended meaning.
