(Built-in) way in JavaScript to check if a string is a valid number

Question

I\'m hoping there\'s something in the same conceptual space as the old VB6 IsNumeric() function?

Answer 1

Using plain JavaScript:

Number.isNaN(Number('1')); // false
Number.isNaN(Number('asdf')); // true

Using Lodash:

_.isNaN(_.toNumber('1')); // false
_.isNaN(_.toNumber('asdf')); // true
