Go Programming Language : Basics

  • Go is a popular programming language created by Google known for its simplicity, speed, and built-in concurrency support.
  • Variables in Go need specific types, and declarations can include or exclude initial values.
  • Constants in Go are set during compile time and can only be numbers, strings, or booleans.
  • Control structures in Go, like for loops and if-else statements, have a clean and familiar syntax.
  • Slices in Go must contain elements of the same type and are more flexible and resizable than arrays.
  • Maps in Go are unordered collections of key-value pairs, where each key must be unique.
  • Go functions are first-class citizens, allowing them to be passed as arguments and returned from functions.
  • Closures in Go are anonymous functions that can access variables from their enclosing functions.
  • Structs in Go are collections of fields, similar to classes in other languages but without inheritance.
  • Interfaces in Go define method signatures, allowing types to implement them without explicit declarations.
