How to Initialize a Struct in Go (Literal, New, and Zero Value)

You initialize a Go struct using a literal for immediate values, new() for a zero-value pointer, or by declaring a variable for the zero value. Use the literal syntax to set fields directly, new(Type) to allocate a pointer to a zeroed struct, or var s Type to create a zeroed value on the stack.

// Literal: Creates a value with specific fields
s1 := MyStruct{Field1: 10, Field2: "hello"}

// new(): Returns a pointer to a zero value
s2 := new(MyStruct)

// Zero Value: Declares a variable with default values
var s3 MyStruct

Initializing a struct is like preparing a container before you put things in it. You can build it with items already inside (literal), grab an empty box and a handle to it (new), or just declare that a box exists on the table (zero value). You choose the method based on whether you need a pointer or if you have data ready to insert immediately.
