Schema - Function

The .function method is used to validate whether a given value is of type function. It ensures that the input is a valid function, making it useful for validating function-type data such as event handlers, callbacks, or any other function-based logic in your application.

This method is crucial when you need strict type validation, ensuring that only valid functions are allowed.

Examples

.validate()

Validates if the value is a function:

import { schema } from "vkrun"
 
const schemaValidation = schema().function()
 
const validateA = schemaValidation.validate(() => {}) // Valid function
const validateB = schemaValidation.validate("test")   // Invalid, string is not a function
 
console.log(validateA) // true
console.log(validateB) // false
