Functions ¶
func ArrEvery ¶
ArrEvery 循环数组，并在fn()返回false时提前结束循环
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrEvery(arr, func(val int, idx int) bool {
return val > 0
}))
fmt.Println(ArrEvery(arr, func(val int, idx int) bool {
return val > 1
}))
Output: true false
func ArrFilter ¶
ArrFilter 元素筛选，fn()返回true的元素保留
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrFilter(arr, func(val int, idx int) bool {
return val%2 == 0
}))
Output: [2 4]
func ArrFind ¶
ArrFind 查找元素：返回fn()首次为true的元素，否则返回
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrFind(arr, func(val int, idx int) bool {
return val%2 == 0
}))
Output: 2
func ArrIncludes ¶
func ArrIncludes[V comparable, T []V](arr T, val V) bool
ArrIncludes 判断数组是否包含指定元素
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrIncludes(arr, 0))
fmt.Println(ArrIncludes(arr, 1))
Output: false true
func ArrJoin ¶
ArrJoin 将数组元素转为string，为使用sep拼接
Example ¶
arr := []interface{}{1, 2, 3, 4, 5}
fmt.Println(ArrJoin(arr, "x"))
Output: 1x2x3x4x5
func ArrMap ¶
ArrMap 元素重构：使用fn()的返回值替换原值
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrMap(arr, func(v int, i int) int {
return v * 2
}))
Output: [2 4 6 8 10]
func ArrPop ¶
func ArrPop[V any, T []V](arr *T) V
ArrPop 从数组中移除最后一个元素，并返回
- 无可移除元素时返回指定类型的空值
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrPop(&arr))
fmt.Println(arr)
Output: 5 [1 2 3 4]
func ArrShift ¶
func ArrShift[V any, T []V](arr *T) V

- 无可移除元素时返回指定类型的空值
Example ¶

return val > 0
}))
fmt.Println(ArrSome(arr, func(val int, idx int) bool {
return val > 5
}))

func ArrSplice ¶
ArrSplice 从数组arr的起始位置start开始，删去length个元素，并将val拼接至最后，返回删除的元素切片
- 若start为负数，则从尾部开始算，如：-5，表示从倒数第5个元素开始
- 此方法传入的arr为指针(*T)，会改变原数组
Example ¶
arr := []int{1, 2, 3, 4, 5}
fmt.Println(ArrSplice(&arr, 2, 2, 7, 8, 9))
fmt.Println(arr)
Output: [3 4] [1 2 5 7 8 9]
func Decode ¶
func Decode[T comparable](val T, matches ...T) (v T)

1. 若某组的首个值与val相等，则返回该组第2个值
2. 若某组仅1个值，则直接返回该值
3. 否则返回与val相同类型的空值
Example ¶
fmt.Println(Decode(5, 1, 10, 5, 50))
fmt.Println(Decode(5, 1, 10, 3, 30))
fmt.Println(Decode(5, 1, 10, 3, 30, 25))
