Elixir is a dynamic, functional language for building scalable and maintainable applications.
Elixir leverages the Erlang VM, known for running low-latency, distributed, and fault-tolerant systems. Elixir is successfully used in web development, embedded software, data ingestion, and multimedia processing, across a wide range of industries. Here is a peek:
Performance feature's of elixir:
Scalability
- All Elixir code runs inside lightweight threads of execution (called processes) that are isolated and exchange information via messages
Erlang compatible
- Elixir runs on the Erlang VM giving developers complete access to Erlang's ecosystem, used by companies like Heroku, WhatsApp, Klarna and many more to build distributed, fault-tolerant applications
Fault-tolerance
- To cope with failures, Elixir provides supervisors which describe how to restart parts of your system when things go awry, going back to a known initial state that is guaranteed to work
If you haven’t yet installed Elixir, visit installation page. Once you are done, you can run
elixir --version
to get the current Elixir version.
let’s start by running iex
means interactive elixir
some basic code
iex(1)> 40 + 2
42
iex(2)> "hello" <> " world"
"hello world"
iex> String.length("The quick brown fox jumps over the lazy dog")
43
Support for binary, octal, and hexadecimal numbers comes built in:
iex> 0b0110
6
iex> 0o644
420
iex> 0x1F
31
ATOMS
iex> :apple
:apple
iex> :orange
:orange
iex> :apple == :apple
true
iex> :apple == :orange
false
iex> true == :true
true
You can print a string using the IO.puts/1
function from the IO module
iex> IO.puts("hello\nworld")
hello
world
:ok
IO.puts/1
function returns the atom :ok after printing.
