在for循环中获取中间结果

var results = [];
for (var i = 0; i < 10; i++) {
  var result = i * 2;
  results.push(result);
}
console.log(results); // 输出 [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]

def get_results():
    for i in range(10):
        result = i * 2
        yield result

results = list(get_results())
print(results) # 输出 [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]

import java.util.stream.IntStream;

int[] results = IntStream.range(0, 10)
                        .map(i -> i * 2)
                        .toArray();
System.out.println(Arrays.toString(results)); // 输出 [0, 2, 4, 6, 8, 10, 12, 14, 16, 18]
