javascript replace array of numbers by array of keys : <p>I have this random score (a number) between 0-72.</p>

<p>Each score number has a key number that I have set. (look below)</p>

<p>I need to retrieve the key number by using a function.</p>

<p><strong>Example:</strong></p>

<pre><code>function scoreToKey(score) {
     // the mystery code goes here
     return PERCENTAGE;
}

scoreToKey(100);  // needs to return 100
scoreToKey(72);   // needs to return 100
scoreToKey(50);   // needs to return 39
scoreToKey(44);   // needs to return 4
scoreToKey(29);   // needs to return -92
scoreToKey(12);   // needs to return -100
scoreToKey(0);    // needs to return -100
</code></pre>

<p>I figure you need to use arrays somehow but I can't figure out how.</p>

<p><strong>These are my key values:</strong></p>

<pre><code>score | key
72  100
71  99
70  98
69  97
68  96
67  95
66  94
65  92
64  90
63  87
62  84
61  81
60  78
59  75
58  72
57  69
56  65
55  61
54  57
53  53
52  49
51  44
50  39
49  34
48  28
47  22
46  16
45  10
44  4
43  ‎-2
42  ‎-8
41  ‎-16
40  ‎-24
39  ‎-32
38  ‎-40
37  48
36  56
35  ‎-64
34  ‎-70
33  ‎-76
32  ‎-82
31  ‎-68
30  ‎-90
29  ‎-92
28  ‎-94
27  ‎-96
26  ‎-98
25  ‎-99
1-24    ‎-100

<p>I would really appreciate your help, I can't figure this out and I also don't know what to search for really.</p>

<p>By the way, your code can be in ES6, I don't mind :) Thanks in advance</p>
