# Slice-Helper
It's just a convinience to work with slices.
## Examples
Consider these data for the next examples:
```go
var programmingLanguages = []ProgrammingLanguage{
{Id: 1, Name: "JavaScript", ReleasedYear: 1995, GithutRank: 1, PyplRank: 3},
{Id: 3, Name: "Java", ReleasedYear: 1995, GithutRank: 3, PyplRank: 2},
{Id: 2, Name: "Python", ReleasedYear: 1991, GithutRank: 2, PyplRank: 1},
{Id: 4, Name: "TypeScript", ReleasedYear: 2012, GithutRank: 7, PyplRank: 10},
{Id: 5, Name: "C#", ReleasedYear: 2000, GithutRank: 9, PyplRank: 4},
}
```
### **Find**
```go
p := collections.Find(programmingLanguages, func(p ProgrammingLanguage) bool {
return p.Id == 4
})
fmt.Println(*p)
```
#### Output
```
{4 TypeScript 2012 7 10}
```
### **Filter**
```go
languages := collections.FilterArray(programmingLanguages, func(p ProgrammingLanguage) bool {
return p.GithutRank > 6
})
fmt.Println(languages)
```
#### Output
```
[{4 TypeScript 2012 7 10} {5 C# 2000 9 4}]
```
### **Map**
```go
langNames := collections.MapArray(programmingLanguages, func(p ProgrammingLanguage) string {
return p.Name
})
fmt.Println(langNames)
```
#### Output
```
[JavaScript Java Python TypeScript C#]
```
### **Some**
```go
shouldBeTrue := collections.Some(programmingLanguages, func(p ProgrammingLanguage) bool {
return p.GithutRank == 7
})
shouldBeFalse := collections.Some(programmingLanguages, func(p ProgrammingLanguage) bool {
return p.GithutRank == 4
})
fmt.Println("shouldBeTrue: ", shouldBeTrue, "shouldBeFalse: ", shouldBeFalse)
```
#### Output
```
shouldBeTrue: true shouldBeFalse: false
```
### **Every**
```go
shouldBeTrue = collections.Every(programmingLanguages, func(p ProgrammingLanguage) bool {
return p.GithutRank < 10
})
shouldBeFalse = collections.Every(programmingLanguages, func(p ProgrammingLanguage) bool {
return p.GithutRank > 4
})
fmt.Println("shouldBeTrue: ", shouldBeTrue, "shouldBeFalse: ", shouldBeFalse)
```
#### Output
```
shouldBeTrue: true shouldBeFalse: false
```
### **Group**
```go
sumOfRankings := collections.Group(programmingLanguages, func(p ProgrammingLanguage, amount int) int {
return p.GithutRank + amount
})
fmt.Println("Some of Rankings: ", sumOfRankings)
```
#### Output
```
Sum of Rankings: 22
```
