Transformation

This section contains functions that transform a slice into another slice. Results are returned as a new slice.

Map

Map applies a function to each element in a slice and returns a new slice.

Usage:

slice.Map([]int{1, 2, 3}, func(v int) int { return v * 2 }) // []int{2, 4, 6}

Filter

Filter applies a condition function to each element in a slice and returns a new slice with only the elements that meet the condition.

Usage:

slice.Filter([]int{1, 2, 3}, func(v int) bool { return v > 1 }) // []int{2, 3}

Chunks

Chunks splits a slice into smaller slices of a given size.

Usage:

slice.Chunks([]int{1, 2, 3, 4, 5}, 2) // [[1 2] [3 4] [5]]

Cartesian

Cartesian returns a new slice with all possible combinations of elements from provided slices.

Usage:

slice.Cartesian([]int{1, 2}, []int{3, 4}) // [[1 3] [1 4] [2 3] [2 4]]

Limit

Limit returns a new slice with the first n elements from the provided slice.

Usage:

slice.Limit([]int{1, 2, 3}, 2) // []int{1, 2}

Unique

Unique returns a new slice with only unique elements from the provided slice.

Usage:

slice.Unique([]int{1, 2, 2, 3}) // []int{1, 2, 3}
