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.

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 Map Example | Maps in Go Tutorial Explained

Golang map is an inbuilt data type that has keys that are unique within the map while the values may or may not be the same. The map data structure in Golang is used for fast lookups, retrieval, and deletion of the data based on keys; that is why it is one of the most used data structures in computer science. Go map is an unordered collection of key-value pairs. They map keys to values.

Golang Map Example

One of the most useful data structures in computer science is the hash table. Many hash table implementations exist with varying properties, but in general, they offer fast lookups, adds, and deletes. Go provides a built-in map type that implements a hash table.

Go provides another essential data type named the map which maps unique keys to values. A key is an object that you use to retrieve the value at a later date. Given a key and a value, you can store the value in a Map object. After the value is stored, you can retrieve it by using its key.

There are also other data types available unlike maps for example  arrays,  structs, and  slice in Golang. Let’s start our Golang maps tutorial.

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 ().
