## Description
|
|
<section id='description'>
|
|
|
|
In functional programming, we prefer immutable values over mutable values.
|
|
|
|
Mutable values (declared with <code>var</code> or `let`) can lead to unexpected behaviors and bugs. Values declared with `const` cannot be reassigned, which makes using them easier because you don't have to keep track of their values.
|
|
|
|
Start by creating an empty `infixToFunction` object using `const`.
