This example creates a table and then uses APPEND FROM ARRAY to append a record to the new table. Copy LOCAL ARRAY aNewRec(3) * Create the table CREATE TABLE Test FREE (Object C(10), Color C(16), SqFt n(6,2)) SCATTER TO aNewRec BLANK && Create a new array from the table aNew...
Append operations that trigger reallocation have a performance cost, but they occur less and less often as the array grows larger. If you know approximately how many elements you will need to store, use the reserveCapacity(_:) method before appending to the array to avoid intermediate ...

}, {} as Record<Key, Value>) // 初始化累加器 `acc` 为一个空对象。 } 方法流程说明: 函数接收一个数组 array,一个 getKey 函数用于提取每个元素的键,以及一个可选的 getValue 函数用于提取每个元素的值。 如果没有提供 getValue 函数,则使用一个默认的函数,这个函数简单地将元素本身作为值。 使用...
