= `array` A <<ref_value>> stores an instance of <<ref_array>> as the underlying representation for a JSON array. Instances of the __array__ type function identically to a {std_vector} of <<ref_value>>. Additionally, all values inserted into the container will use the same <<ref_storage_ptr>> as the container itself. An empty array may be constructed without incurring any memory allocations using the <<default_memory_resource,default memory resource>>. A <<ref_storage_ptr>> can also be explicitly specified: Initializer lists can be used to construct objects with initial contents. These constructors may allocate memory and throw: Alternatively, elements may be inserted after construction: Similar to its standard library counterpart, elements may be accessed directly by their 0-based index with bounds checking using <<ref_array_at>>, or without bounds checking using <<ref_array_operator_lb_rb>>: For the complete listing of all available member functions and nested types, see the reference page for <<ref_array>>. Formatted Output When an <<ref_array>> is formatted to a {std_ostream}, the result is a valid JSON. That is, the array will be output with square brackets and the comma separated list of values, as per the JSON specification.
