{% raw %} Adopt modern JavaScript and Ember syntax patterns instead of legacy approaches to improve code readability and maintainability. Key modern patterns to use: **Native private methods** - Use `#` prefix instead of underscore convention: ```javascript // ❌ Legacy _buildEventObject(from, to) { // implementation } // ✅ Modern #buildEventObject(from, to) { // implementation } ``` **Boolean attributes** - Use proper boolean syntax instead of explicit true/false: ```handlebars ``` **Optional chaining** - Use `?.` for cleaner conditional calls: ```javascript // ❌ Legacy if (this.onBlur) { this.onBlur(this.normalize(this.hexValue)); } // ✅ Modern this.onBlur?.(this.normalize(this.hexValue)); ``` **Modern array methods** - Use `.at()` for array access: ```javascript // ❌ Legacy const lastWord = words[words.length - 1]; // ✅ Modern const lastWord = words.at(-1); ``` These modern syntax patterns are now well-supported and provide cleaner, more expressive code that aligns with current JavaScript and Ember best practices. {% endraw %}
