number primitive that conforms as valid array length
array-length/coerce
Follows safe-integer/coerce
but returns null
in place of values which are below 0
```javascript const coerceToArrayLength = require("type/safe-integer/coerce");
coerceToArrayLength("12.95"); // 12 coerceToArrayLength(9007199254740992); // null coerceToArrayLength(null); // null ```
array-length/ensure
If given argument is an array length coercible value (via array-length/coerce
) returns result number.
Otherwise TypeError
is thrown.
```javascript const ensureArrayLength = require("type/array-length/ensure");
ensureArrayLength(12.93); // "12" ensureArrayLength(9007199254740992); // Thrown TypeError: 9007199254740992 is not a valid array length ```
