In this example, the expression `hello + ” world”` creates a temporary std::string, which is converted to a std::string_view before the constructor of X is called. X stores a string_view to that temporary string, and that temporary string is destroyed at the end of the full expressio...
String.prototype.constructor用于创造对象的原型对象的特定的函数。 String.prototype.length返回了字符串的长度。 N用于访问第N个位置的字符,其中N是小于 length和0之间的正整数。这些属性都是“只读”性质,不能编辑。 方法 跟HTML无关的方法 String.prototype.charAt()返回特定位置的字符。 String.prototype.charCodeA...
