補充說明

當使用 each 遍歷陣列時，可以使用 {{@index}} 引用當前循環索引

{{#each array}} {{@index}}: {{this}} {{/each}}

              
              {{#each array}} {{@index}}: {{this}} {{/each}}

此外，對於物件迭代，{{@key}} 引用當前鍵名

{{#each object}} {{@key}}: {{this}} {{/each}}

              
              {{#each object}} {{@key}}: {{this}} {{/each}}
