将范围复制到目标并返回目标范围

const sourceArray = [1, 2, 3, 4, 5];
const targetArray = sourceArray.slice();

console.log(targetArray); // 输出 [1, 2, 3, 4, 5]

source_list = [1, 2, 3, 4, 5]
target_list = source_list[:]

print(target_list) # 输出 [1, 2, 3, 4, 5]

int[] sourceArray = {1, 2, 3, 4, 5};
int[] targetArray = new int[sourceArray.length];
System.arraycopy(sourceArray, 0, targetArray, 0, sourceArray.length);

System.out.println(Arrays.toString(targetArray)); // 输出 [1, 2, 3, 4, 5]
