javascript之是否有可能以某种方式缩短 switch 语句也许有一个循环

无论使用哪种编程语言，有哪些选项可以缩短具有许多类似情况的长 switch 语句？

根据我的搜索，我找到了类似 this one 的答案但我的情况各不相同，只有一个整数在循环中变化。

我经常在 bash/PHP/Python/JavaScript 中使用以下 switch 语句构造，我正在寻找更短的版本:

switch ($device) { 
    // 2ghz 
    case "n2": 
        return 1; 
        break; 
    case "nne2": 
        return 2; 
        break; 
    case "ne2": 
        return 3; 
        break; 
    case "ene2": 
        return 4; 
        break; 
    case "e2": 
        return 5; 
        break; 
    case "ese2": 
        return 6; 
        break; 
    case "se2": 
        return 7; 
        break; 
    case "sse2": 
        return 8; 
        break; 
    case "s2": 
        return 9; 
        break; 
    case "ssw2": 
        return 10; 
        break; 
    case "sw2": 
        return 11; 
        break; 
    case "wsw2": 
        return 12; 
        break; 
    case "w2": 
        return 13; 
        break; 
    case "wnw2": 
        return 14; 
        break; 
    case "nw2": 
        return 15; 
        break; 
    case "nnw2": 
        return 16; 
        break; 
 
    // 5ghz 
    case "n5": 
        return 17; 
        break; 
    case "nne5": 
        return 18; 
        break; 
    case "ne5": 
        return 19; 
        break; 
    case "ene5": 
        return 20; 
        break; 
    case "e5": 
        return 21; 
        break; 
    case "ese5": 
        return 22; 
        break; 
    case "se5": 
        return 23; 
        break; 
    case "sse5": 
        return 24; 
        break; 
    case "s5": 
        return 25; 
        break; 
    case "ssw5": 
        return 26; 
        break; 
    case "sw5": 
        return 27; 
        break; 
    case "wsw5": 
        return 28; 
        break; 
    case "w5": 
        return 29; 
        break; 
    case "wnw5": 
        return 30; 
        break; 
    case "nw5": 
        return 31; 
        break; 
    case "nnw5": 
        return 32; 
        break; 
 
    // 24ghz 
    case "n24": 
        return 33; 
        break; 
    case "nne24": 
        return 34; 
        break; 
    case "ne24": 
        return 35; 
        break; 
    case "ene24": 
        return 36; 
        break; 
    case "e24": 
        return 37; 
        break; 
    case "ese24": 
        return 38; 
        break; 
    case "se24": 
        return 39; 
        break; 
    case "sse24": 
        return 40; 
        break; 
    case "s24": 
        return 41; 
        break; 
    case "ssw24": 
        return 42; 
        break; 
    case "sw24": 
        return 43; 
        break; 
    case "wsw24": 
        return 44; 
        break; 
    case "w24": 
        return 45; 
        break; 
    case "wnw24": 
        return 46; 
        break; 
    case "nw24": 
        return 47; 
        break; 
    case "nnw24": 
        return 48; 
        break; 
 
    default: 
        return 0; 
        break; 
} 

请您参考如下方法:

在 Python 中你可以使用像这样简单的东西，如果你的返回值很简单的话:

items = ["n2","nne2","ne2","ene2", ...] 
for idx, key in enumerate(items, start=1): 
    if device == key: 
        result = idx 
    result = 0 

或者如果您希望返回值更复杂:

my_dict = { 
    "n2": 1, 
    "nne2": 2, 
    "ne2": 3, 
    "ene2": 4, 
    ...} 
 
for key, value in my_dict.items(): 
    if device == key: 
        result = value 
    result = 0
