Go Slice Append Example | Golang Append Tutorial

Go Slice Append Example | Golang Append Tutorial is today’s topic. The built-in append function appends any number of elements to the end of a  slice. Append returns the updated slice and it does not modify the existing one. So it is Pure function in terms of Javascript. The resulting value of append() function is a slice containing all the elements of the original slice plus the provided values.

Go Slice Append Example

In Golang, a slice is a reference to the contiguous segment of the array. Slice is the pointer, with additional properties about an array.

A slice is consists of 3 fields.

• The Pointer to the underlying array.
• Length of the slice.
• The capacity of the slice.

Slicing does not copy the slice’s data. It creates the new slice value that points to an original array. It makes slice operations as efficient as manipulating the array indices.

What's new in the go 1.15

Go announced Go 1.15 version on 11 Aug 2020. Highlighted updates and features include Substantial improvements to the Go linker, Improved allocation for small objects at high core counts, X.509 CommonName deprecation, GOPROXY supports skipping proxies that return errors, New embedded tzdata package, Several Core Library improvements and more.

As Go promise for maintaining backward compatibility. After upgrading to the latest Go 1.15 version, almost all existing Golang applications or programs continue to compile and run as older Golang version.

Golang Array Example | Arrays in Go Tutorial Explained

Golang array is a fixed-size collection of items of the same type. The items of an array are stored sequentially and can be accessed using their index. If we want to declare an array in Go, a programmer specifies the type of the elements and the number of items required by an array.

Golang array example

Golang programming language provides a data structure called an** array**, which can store the fixed-size sequential collection of items of the same type.

The array is used to store the collection of data, but it is often more useful to think of the array as the collection of variables of the same type.

Instead of declaring individual variables, such as no1, no2, …, and no99, you declare one array variable such as numbers and use no[0], no[1], and …, no[99] to represent individual variables.

Anatomy of Conditional Statements and Loops in Go

Go provides if/else and switch conditional statements for code execution based on certain conditions. To execute some code over and over again, we have the for loop.

The if/else conditional statement

Go provides if, if-else, if-else if-else variants of if/else statement we are familiar with. It is used to check a condition, and execute some code when the condition is true or false.

The if condition

Simple use of if condition is demonstrated below. Unlike most of the programming languages, Go does not allow to wrap the condition inside parenthesis ().
