Create a native TypeError
object by passing the expected type and the actual value.
Note: No validation is done; only type & value formatting.
const TypeError = require('type-error');
const foo = new Foo();
if (!(foo instanceof Bar)) {
throw TypeError(Bar, foo); // 'Expected a Bar instance, got a Foo instance'
}
The first argument should be the constructor of the expected type, or a string describing the expected value. The second argument can be anything.
TypeError(Function, 1) // 'Expected a function, got a number'
TypeError(Array, true) // 'Expected an array, got true'
TypeError(Number, NaN) // 'Expected a number, got NaN'
TypeError('null', {}) // 'Expected null, got an object'
