by 凤之兮原 @kongmingLatern

With type ``CountElementNumberToObject``, get the number of occurrences of every item from an array and return them in an object. For example: ~~~ts type Simple1 = CountElementNumberToObject<[]> // return {} type Simple2 = CountElementNumberToObject<[1,2,3,4,5]> // return { // 1: 1, // 2: 1, // 3: 1, // 4: 1, // 5: 1 // } type Simple3 = CountElementNumberToObject<[1,2,3,4,5,[1,2,3]]> // return { // 1: 2, // 2: 2, // 3: 2, // 4: 1, // 5: 1 // } ~~~
