-<p>Booleans, null, strings and numbers are written the same way as in javascript. Just like everything else in jq, these simple values take an input and produce an output - <code>42</code> is a valid jq expression that takes an input, ignores it, and returns 42 instead.</p>

-<p>As in JSON, <code>[]</code> is used to construct arrays, as in <code>[1,2,3]</code>. The elements of the arrays can be any jq expression. All of the results produced by all of the expressions are collected into one big array. You can use it to construct an array out of a known quantity of values (as in <code>[.foo, .bar, .baz]</code>) or to “collect” all the results of a filter into an array (as in <code>[.items[].name]</code>)</p>

|

|
|
|
|
-<p>Once you understand the “,” operator, you can look at jq’s array syntax in a different light: the expression <code>[1,2,3]</code> is not using a built-in syntax for comma-separated arrays, but is instead applying the <code>[]</code> operator (collect results) to the expression 1,2,3 (which produces three different results).</p>
|
|
|
+在JSON中，`[]` 用来构建数组,如[1,2,3]。数组的元素可以是任意的jq表达式,所有这些表达式产生的结果都被合起来组成一个大数组。
|
|
|
+你可以用它来构建一个由已知数量的值组成的数组（比如`[.foo,.bar,.baz]`）或者是"收集"一个过滤器产生的所有输出到一个数组里(比如:`[.items[].name]`)。
|
|
|
|
|
|
-<p>If you have a filter <code>X</code> that produces four results, then the expression <code>[X]</code> will produce a single result, an array of four elements.</p>
|
|
|
+一旦你理解了","操作符，就可以从不同角度看jq的数组语句语法:表达式`[1,2,3]`不适使用内建的逗号分隔数组的语法，而是把`[]`操作符应用在表达式1,2,3上面(这个表达式产生3个输出结果。)
|
|
|
|
|
|
+如果你有一个过滤器 `X`生成4个输出结果，那么表达式`[X]`会生成一个由四个元素的单个数组的输出。

<p>Like JSON, <code>{}</code> is for constructing objects (aka dictionaries or hashes), as in: <code>{"a": 42, "b": 17}</code>.</p>
|
|
|
|
|
|
<p>If the keys are “sensible” (all alphabetic characters), then the quotes can be left off. The value can be any expression (although you may need to wrap it in parentheses if it’s a complicated one), which gets applied to the {} expression’s input (remember, all filters have an input and an output).</p>
