# Variable
### Intro
LLMs have the ability to recall and reference the data we declared.
We could compare this ability to declaring variables in any programming language.
### How it work ?
You could use "ANY" method to declare a variable.
```
i.e.
a = "hello world"
a => "hello world"
a -> "hello world"
helloworld
{a}helloworld{a}
a > "hello world"
a => hello world
"""a
hello world
"""
```

A software developer could consider an LLM as a 'natural coding language.' It has similar abilities to other programming languages.
