963 markdown files reformatted with the repository's pinned prettier so pnpm format:check covers the folded tree like every other repo file. The formatter's embedded-language pass also normalized code fences (TS semicolons, closed HTML tags in examples, lowercased CSS hex colors, one renumbered list that skipped an index). Alphanumeric token deltas vs the fold commit were audited file-by-file; all are formatter-equivalent markup normalizations plus the four sanitized skills.

useArrayJoin
Reactive Array.join
Usage
Use with array of multiple refs
import { useArrayJoin } from '@vueuse/core';
const item1 = ref('foo');
const item2 = ref(0);
const item3 = ref({ prop: 'val' });
const list = [item1, item2, item3];
const result = useArrayJoin(list);
// result.value: foo,0,[object Object]
item1.value = 'bar';
// result.value: bar,0,[object Object]
Use with reactive array
import { useArrayJoin } from '@vueuse/core';
const list = ref(['string', 0, { prop: 'val' }, false, [1], [[2]], null, undefined, []]);
const result = useArrayJoin(list);
// result.value: string,0,[object Object],false,1,2,,,
list.value.push(true);
// result.value: string,0,[object Object],false,1,2,,,,true
list.value = [null, 'string', undefined];
// result.value: ,string,
Use with reactive separator
import { useArrayJoin } from '@vueuse/core';
const list = ref(['string', 0, { prop: 'val' }]);
const separator = ref();
const result = useArrayJoin(list, separator);
// result.value: string,0,[object Object]
separator.value = '';
// result.value: string0[object Object]
separator.value = '--';
// result.value: string--0--[object Object]
