Code for smart contracts in Ethereum is written in a high-level language such as Serpent, LLL, Solidity, or Viper and is converted into the bytecode that EVM understands for it to be executed.
Solidity is one of the high-level languages that has been developed for Ethereum with JavaScript like syntax to write code for smart contracts.
A Complete Guide to Understanding This Blockchain Concept
Once the code is written, it is compiled into bytecode that’s understandable by the EVM using the Solidity compiler called solc.
Official Solidity documentation is
Low-level Lisp-like Language (LLL) is another language that is used to write smart contract code.
Serpent is a Python-like high-level language that can be used to write smart contracts for Ethereum.
Vyper is a newer language which has been developed from scratch to achieve a secure, simple, and auditable language.

Why This Matters for Blockchain Technology
LLL and Serpent are no longer supported by the community and their usage has almost diminished.
For example, a simple program in Solidity is shown as follows: pragma solidity ^0.4.0; contract Test1 uint x=2; function addition1(uint x) returns (uint y) y=x+2; This program is converted into bytecode. subsection.
Details on how to compile Solidity code with examples will be given in , Development Tools and Frameworks.
