Next, you need to include the type declaration file for Underscore in your TypeScript project. If you're using a module-based system (such as ES6 modules), you can import the type declaration like this:

index.ts94 chars5 lines

If you're not using a module-based system, you can use a triple-slash directive to reference the type declaration file in your TypeScript code:

index.ts128 chars5 lines

Then, you can use the `isNaN`

function from the Underscore library like any other function by passing it a value and getting a boolean as a result.

index.ts67 chars4 lines

The `isNaN`

function is used to determine whether a value is NaN (not a number) or not. If the value is not a number, the function will return `true`

. Otherwise, it will return `false`
