There are 3 components of slice:a) Pointer: Points to the start position of slice in the underlying array;b) length (type is int): the number of the valid elements of the slice;b) capacity (type is int): the total number of slots of the slice.Check the following code:package mainimport ( "fmt" "unsafe")func main() { var s1 []int fmt.Println(unsafe.Sizeof(s1))}The result is 24 on my 64-bit system (The pointer and int both occupy 8 bytes).In the next example, I will use gdb to poke the internals of slice. The code is like this:package mainimport "fmt"func main() { s1 := make([]int, 3, 5) ...

You may notice that there is no max/min function provided to compare the maximum/minimum of two or more integers if you are a GoLang developer with some experience . In other languages, these functions are provided as part of the core lib functions. Have you wondered why? Indeed GoLang provides max/min function in math package, but they are used for comparing float64 data type. The signature of these two functions aremath.Min(float64, float64) float64math.Max(float64, float64) float64The reason why GoLang provides the max/min function for comparing float64 numbers are that floating n...

In some cases, there might be some JavaScript code needs to be ran in a GoLang project. Fortunately, there are a few libraries which support running JavaScript in GoLang. The most famous one would be v8. This is a Go API for the famous v8 JavaScript engine originally developed for the Chrominum project and the foundation of NodeJS.In this post, we will show some simple steps to get v8 working in a GoLang program on MacOS. First you need to install the package so that you can import it. Run belowgo get github.com/augustoroman/v8Unluckily you would encounter an error where some header file ...

nil check is frequently seen in GoLang code especially for error check since GoLang's special error handling convention. In most cases, nil check is straight forward, but in interface case, it's a bit different and special care needs to be taken.Take a look at below code snippet and guess what the output will be.package mainimport ( "bytes" "fmt" "io")func check(w io.Writer) { if w != nil { fmt.Println("w is not nil") } fmt.Printf("w is %+v\n", w)}func main() { var b *bytes.Buffer check(b) fmt.Printf("b is %+v", b)}The output will be:w is not nilw is b is In the check() method, you would expe...
