Abstract Relational Comparison

-

The comparison _x_ < _y_, where _x_ and _y_ are values, produces *true*, *false*, or *undefined* (which indicates that at least one operand is *NaN*). In addition to _x_ and _y_ the algorithm takes a Boolean flag named _LeftFirst_ as a parameter. The flag is used to control the order in which operations with potentially visible side-effects are performed upon _x_ and _y_. It is necessary because ECMAScript specifies left to right evaluation of expressions. The default value of _LeftFirst_ is *true* and indicates that the _x_ parameter corresponds to an expression that occurs to the left of the _y_ parameter's corresponding expression. If _LeftFirst_ is *false*, the reverse is the case and operations must be performed upon _y_ before _x_. Such a comparison is performed as follows:

抽象关系比较

比较_x_ < _y_，_x_ 和 _y_ 都是 ECMAScript 语言值，将可能产生*true*, *false*, 或 *undefined*（表示其中至少有一个操作数为 *NaN*）。除了 _x_ 和 _y_ 之外，算法会使用一个名为 _LeftFirst_ 的 Boolean 类型标志，作为一个参数。这个标志用于控制对 _x_ 和 _y_ 执行潜在可见副作用操作的顺序。这是有必要的，因为 ECMAScript 规定计算是从左向右的。_LeftFirst_ 的默认值为 *true*，表示 _x_ 参数相应表达式在 _y_ 参数相应的表达式的左测。如果 _LeftFirst_ 为 *false*，则必须在 _x_ 之前执行 _y_。具体比较执行如下：

The comparison of Strings uses a simple lexicographic ordering on sequences of code unit values. There is no attempt to use the more complex, semantically oriented definitions of character or string equality and collating order defined in the Unicode specification. Therefore String values that are canonically equal according to the Unicode standard could test as unequal. In effect this algorithm assumes that both Strings are already in normalized form. Also, note that for strings containing supplementary characters, lexicographic ordering on sequences of UTF-16 code unit values differs from that on sequences of code point values.

字符串类型的比较使用码元值序列的简单词典排序。这里没有尝试使用 Unicode 规范定义的更复杂的，基于语义的字符或字符串相等，以及排序顺序进行比较。因此，根据 Unicode 标准在规范上相等的字符串值可能测试为不相等。实际上，该算法假设了两个值是已经标准化的值。另外还需注意，对于包含补充字符的字符串，UTF-16 码元值序列与普通码元值序列的词典排序是不同的。
