I want to access the first item of an array inside a meteor template, I'm using this syntax :
我想访问流星模板中的数组的第一项,我正在使用这种语法:
<p>{{array[0]}}</p>
However it doesn't seem like it's working. I don't want to iterate through values using {{#each}}
, just pick the first one from the array.
然而,它似乎并没有起作用。我不想使用{{#each}}迭代值,只需从数组中选择第一个。

This is just a problem of syntax, the correct one is the following :
这只是语法问题,正确的如下:
<p>{{array.[0]}}</p>
Notice the .
dot between the array property and the brackets (array indexing) notation ?
请注意。数组属性和括号(数组索引)表示法之间的点?
