Other packages similar to lodash.isnumber
is-number
The is-number package is a simple utility that checks if a value is a number. It is similar to lodash.isnumber but is a standalone package without the additional utilities provided by Lodash. It also returns true for number primitives and objects, including NaN.
number-is-nan
The number-is-nan package is a utility that specifically checks if a value is NaN. While it is more specialized than lodash.isnumber, it can be useful in scenarios where you need to specifically identify NaN values.

The is-numeric package checks if a value is numeric, which includes both number primitives and numeric strings. This is slightly different from lodash.isnumber, which does not consider numeric strings as numbers.
