+
+Indents each line in the provided string.

+Omit the third parameter, `indent`, to use a default indentation character of `' '`.
+
+```js
+const indentString = (str, count, indent = ' ') =>
+  str.replace(/^/mg, indent.repeat(count));
+```
+
+```js
+indentString('Lorem\nIpsum', 2); // '  Lorem\n  Ipsum'
+indentString('Lorem\nIpsum', 2, '_'); // '__Lorem\n__Ipsum'
+```
