Function validateNumber

Validates a number or an array of numbers, with a fluent interface.

If passed an array, it will return an ArrayNumberValidator

If passed anything else, it will return a NumberValidator

You can pass the things in as a one key object, and it will automatically set the name for you.

// Validate single numbers
validate(2).gt(1).lt(3); // doesn't throw
validate(3).gt(1).lt(3); // throws
Copy

// Validate in the object fashion so it automatically sets the name
let myVar = 5;
validate({ myVar }).gt(10); // throws `Expected myVar to be greater than 10, got 5`
Copy

// Also used with arrays of numbers
validate([1, 2, 3]).lt(10); // doesn't throw
validate([1, 2, 3]).sumto(6); // doesn't throw
validate([1, 2, 3, 4]).sumtolt(9); // throws
Copy

// All single number validations
validate(1).int();
validate(1).positive();
validate(-1).negative();
validate(1).between(0, 2);
validate(1).betweenEq(1, 2);
validate(1).gt(0);
validate(1).gteq(1);
validate(1).lt(2);
validate(1).lteq(1);
