`isNumber` is a super tiny module that provides a test to see if a value is a finite number.
|
||
|
|
|
||
|
|
By super tiny, I mean like a single line -- however, I tend to use this somewhat frequently, so module it is!
|
||
|
|
|
||
|
|
```js
|
||
|
|
var isNumber = require("isnumber")
|
||
|
|
|
||
|
|
isNumber(13) // true
|
||
|
|
isNumber("1241.12") // true
|
||
|
|
isNumber(0xff) // true
|
||
|
|
|
||
|
|
isNumber(Infinity) // false
|
||
|
|
isNumber("cat") // false
|
||
|
|
isNumber({foo: "bar"}) // false
|
||
|
|
```
