寫出漂亮程式碼的7種方法

很多開發者不願意使用空白，就好像這要收費一樣。我在此並非刻意地新增空白，粗魯地打斷程式碼的連貫性。在實際編寫程式碼的過程中，會很容易地發現在什麼地方加入空白，這不但美觀而且讓讀者易懂，如下：
1 function getSomeAngle() {
2 // Some code here then
3 radAngle1 = Math.atan(slope(center, point1));
4 radAngle2 = Math.atan(slope(center, point2));
5
6 firstAngle = getStartAngle(radAngle1, point1, center);
7 secondAngle = getStartAngle(radAngle2, point2, center);
8
9 radAngle1 = degreesToRadians(firstAngle);
10 radAngle2 = degreesToRadians(secondAngle);
11
12 baseRadius = distance(point, center);
13 radius = baseRadius + (lines * y);
14
15 p1["x"] = roundValue(radius * Math.cos(radAngle1) + center["x"]);
16 p1["y"] = roundValue(radius * Math.sin(radAngle1) + center["y"]);
17
18 pt2["x"] = roundValue(radius * Math.cos(radAngle2) + center["y"]);
19 pt2["y"] = roundValue(radius * Math.sin(radAngle2) + center["y");
20 // Now some more code
21 }
1 function getSomeAngle() {
2 // Some code here then
3 radAngle1 = Math.atan(slope(center, point1));
4 radAngle2 = Math.atan(slope(center, point2));
5
6 firstAngle = getStartAngle(radAngle1, point1, center);
7 secondAngle = getStartAngle(radAngle2, point2, center);
8
9 radAngle1 = degreesToRadians(firstAngle);
10 radAngle2 = degreesToRadians(secondAngle);
11
12 baseRadius = distance(point, center);
13 radius = baseRadius + (lines * y);
14
15 p1["x"] = roundValue(radius * Math.cos(radAngle1) + center["x"]);
16 p1["y"] = roundValue(radius * Math.sin(radAngle1) + center["y"]);
17
18 pt2["x"] = roundValue(radius * Math.cos(radAngle2) + center["y"]);
19 pt2["y"] = roundValue(radius * Math.sin(radAngle2) + center["y");
20 // Now some more code
21 }
