What is the difference between Go's constants and variables?

Question

Jayant Kumar · Accepted Answer

In Go, constants and variables are both used to store values, but they differ in terms of their mutability and scoping.
Constants are declared using the const keyword, followed by the name of the constant and its value. Once a constant is declared, its value cannot be changed. Constants are scoped to the package in which they are declared and can be accessed by any file within the package. Constants are typically used for values that do not change, such as mathematical constants, or for values that are used throughout a program, such as error codes.
Variables are declared using the var keyword, followed by the name of the variable and its initial value (if any). Variables can be changed at any time during the execution of a program. Variables are also scoped to the package in which they are declared, but they can also be scoped to a block or function using the curly braces {}. This means that variables declared inside a block or function are not accessible outside of that block or function. Variables are typically used for values that change during the execution of a program, such as user input, or for values that are specific to a certain part of the program.
