Strings in Golang

Strings in Go are just sequences of characters, and we can perform almost all operations that we can do with an array. We can slice them into different chunks, get their length, and so on.

Let's consider a string like this:

var name = "Coddy"

Similar to slices and arrays, we can get the length using the len() function:

fmt.Println(len(name))

The result will be:

5

To access a specific character based on the index:

var name = "Coddy"
fmt.Println(name[0])

Just like arrays and slices, indexing starts from 0. Running this will get:

99

99 is the Unicode value of the character C. To get the character value, we need to convert the Unicode value to a string using the string() function:

var name = "Coddy"
fmt.Println(string(name[0]))

As a result, we will get the character "C".

We can also slice strings into different chunks like this:

var name = "Coddy"
fmt.Println(name[1:4])

The result will be:

odd

Here, we get the string value "odd" without having to explicitly convert it to a string. In Go, if we access a single specific value using the index, we get the Unicode value, which we call a rune, another data type in Go.
