Array Sorting Functions

ascending

It sorts arrays ascendingly.

• [1,3,4,2].sort(ascending) // [1,2,3,4]

• ['c','d','a','b'].sort(ascending) // ['a','b','c','d']

It also sorts array of objects, but it requires the property name to be sorted by.

[{p:3}, {p:1}, {p:2}].sort(ascending('p')) // [{p:1}, {p:2}, {p:3}]

descending

It sorts arrays descendingly.

• [1,3,4,2].sort(descending) // [4,3,2,1]

• ['c','d','a','b'].sort(descending) // ['d','c','b','a']

It also sorts array of objects, but it requires the property name to be sorted by.

[{p:3}, {p:1}, {p:2}].sort(ascending('p')) // [{p:3}, {p:2}, {p:1}]
