## Description
<section id='description'>
# --description--
Given a text file of many lines, where fields within a line are delineated by a single <code>$</code> character, write a program that aligns each column of fields by ensuring that words in each column are separated by at least one space. Further, allow for each word in a column to be either left justified, right justified, or center justified within its column.

Given a text file of many lines, where fields within a line are delineated by a single `$` character, write a program that aligns each column of fields by ensuring that words in each column are separated by at least one space.

tests:
- text: <code>formatText</code> should be a function.
testString: assert(typeof formatText === 'function');
- text: '<code>formatText</code> with the above input and "right" justification should produce the following: '

## Challenge Seed

`formatText` should be a function.
```js
const testArr = [

'justified,$right$justified',
'or$center$justified$within$its$column.'
];
function formatText(input, justification) {
}
assert(typeof formatText === 'function');
```
</div>
`formatText` with the above input and "right" justification should produce the following:
```js
assert.strictEqual(formatText(testInput, 'right'), rightAligned);
```
### After Test
<div id='js-teardown'>
`formatText` with the above input and "left" justification should produce the following:
```js
assert.strictEqual(formatText(testInput, 'left'), leftAligned);
```
`formatText` with the above input and "center" justification should produce the following:
```js
