Julia： Julia 是一种高级编程语言，由麻省理工学院 (MIT) 的 4 人开发。这种编程语言用于科学计算，是一种开源、高性能、高级、动态的编程语言。 Julia 主要由研究科学家和工程师使用。 Julia 编程语言也可以称为灵活的动态语言，非常适合数值计算和科学计算。 Julia 的编程速度非常快，这就是构建它的原因。它的执行速度非常快。
Perl： Perl 是一种稳定的、跨平台的、通用的编程语言，最初是为文本操作而开发的。它用于广泛的任务，包括系统管理、Web 开发、网络编程、GUI 开发等。Perl 支持过程和面向对象编程。 Perl 非常类似于一种编程语言，它在语法上是 C，并且对于了解 C、C++ 的人来说很容易理解。 Perl 可以嵌入到 Web 服务器中以提高其处理能力，并且它具有 DBI 包，这使得 Web 数据库集成非常容易。
以下是 Julia 和 Perl 之间的一些主要区别：
| Features | Julia | Perl |
|---|---|---|
| License | License associated with Julia is MIT License. | License associated with Perl is GPLv3. |
| Interpreter | Julia does not require use of interpreter. | There is a requirement of interpreter in Perl. |
| Basic Use | For the high performance use, Julia was designed. Julia programs compile to efficient native code for multiple platforms via LLVM. | Perl is a programming language. It was developed first to made the changes to text files. |
| Tag | The tag used for Julia is Multiple Dispatch, Procedural, Functional, JIT, Metaprogramming, OOP. | The tag used for Perl is Programming, functional, Multi-paradigm. |
| Database | Database used in julia are MongoDB, LevelDB, CouchDB, Flat File, MySQL, PostgreSQL. | Database used in perl are MySQL, Microsoft SQL Server 2005, PostgreSQL, cassandra, Oracle, LevelDB, BigTable, Apache, CouchDB, Couchbase, Titan, Flat File, Drizzle, Freebase, teradata, Informix, InterBase, JDBC Compatible, MemcacheDB, StormDB, Redis, MongoDB, firebird, BaseX, Tarantool. |
| Target Audience | The target audience in julia is Beginner Distributed Systems, Scientific computing, Research & Development, Cloud computing, Embedded system | The target audience in perl is System Adminstration, Web Development, Employees, Customers, Vendors, Research & Development, Scientific computing, Financial Services, Enterprise, Beginner, App developer, Data Analysis, Educational use, Government |
| Difficulty Level | The difficulty level in julia consists of Beginner Intermediate, Advanced, Master | The difficulty level in perl consists of only Advanced. |
| Inheritence | Multiple Inheritence is not allowed in julia. | Multiple Inheritence is allowed in perl. |
| Machine Code Generation | Machine Code Generation is required in julia. | Machine Code Generation requirement is not there in perl. |
| Realtime Server Push | Realtime Server Push is there in the Julia. | There is no Realtime Server Push present in perl. |
| VCS | Any of the VCS is supported by julia. | It supports only Git, CVS, Mercurial, Subversion, github |
| Community Driven | Community Driven rating is “good” in julia. | Community Driven rating is “excellent” in perl. |
| HTML Syntax | There is no HTML syntax requirement in julia. | HTML syntax is required in Perl. |
| Native asynchronous operators await | It has Native asynchronous operators await/async. | It does not have Native asynchronous operators await/async. |
| Writing a program | We can write a program in Sublime Text 3, Juno IDE, LightTable. | We can write a program in AWstats. |
两个数字相加的示例程序：
Julia
# Julia program for
# Addition of Two Numbers
# Defining Numbers
x = 10
y = 20
# Adding Two Numbers
z = x + y
# Printing the output
print(z)Perl
# Perl program for
# Addition of Two Numbers
# Defining Numbers
$x = 10;
$y = 20;
# Adding Two Numbers
$z = $x + $y;
# Printing the output
print $z;输出：
30
