- * Safer version of `Array.from` that return `null` if value isn't convertible to array.
- * Also protects against Array-like objects without items.
- *
- * @example
- *
- * safeArrayFrom([ 1, 2, 3 ]) // [1, 2, 3]
- * safeArrayFrom('ABC') // null
- * safeArrayFrom({ length: 1 }) // null
- * safeArrayFrom({ length: 1, 0: 'Alpha' }) // ['Alpha']
- * safeArrayFrom({ key: 'value' }) // null
- * safeArrayFrom(new Map()) // []
