| <h2 class="anchor anchorTargetStickyNavbar_Vzrq" id=为什么选择-fory-javascript>为什么选择 Fory JavaScript？<a href=#为什么选择-fory-javascript class=hash-link aria-label="为什么选择 Fory JavaScript？的直接链接" title="为什么选择 Fory JavaScript？的直接链接" translate=no></a></h2> |
| <ul> |
| <li class=""><strong>跨语言</strong>：在 JavaScript/TypeScript 中序列化，在任意受支持的 Fory 库中反序列化，无需编写粘合代码</li> |
| <li class=""><strong>快速</strong>：首次注册 Schema 时生成并缓存序列化器代码，而不是每次调用都生成</li> |
| <li class=""><strong>支持引用</strong>：启用后支持共享引用和循环对象图</li> |
| <li class=""><strong>显式 Schema</strong>：使用 <code>Type.*</code> 构建器或 TypeScript 装饰器一次性声明字段类型、可空性和多态</li> |
| <li class=""><strong>安全默认值</strong>：可配置的深度检查会拒绝深度超出预期的载荷</li> |
| <li class=""><strong>现代类型</strong>：支持 <code>bigint</code>、typed array、<code>Map</code>、<code>Set</code>、<code>Date</code>、<code>float16</code> 和 <code>bfloat16</code></li> |
