## Quick Take
```js
import { strict as assert } from "node:assert";
import {
chompLeft,
chompRight,
left,
leftSeq,
leftStopAtNewLines,
right,
rightSeq,
rightStopAtNewLines,
} from "string-left-right";
// get the closest non-whitespace character to the left of "d" (which itself
// is at string index 6)
const str = "abc def";
// | |
// 012345678
assert.equal(
`next non-whitespace character to the left of ${str[6]} (index 6) is ${
str[left(str, 6)]
} (index ${left(str, 6)})`,
"next non-whitespace character to the left of d (index 6) is c (index 2)",
);
