less.class.ts

public static isLess<Value extends number>(
  value: any,
  lessValue?: Value
): value is Less<Value> {

    value instanceof this &&
    (typeof lessValue === 'number' ? value.valueOf() === lessValue : true)
  );
}

Generic type variables

Valueextendsnumber

A generic type variable indicates captured type of the supplied lessValue via the return type.

Parameters

value:any

The value of any type to test against the Less instance.

lessValue:Value

An optional value of generic type variable Value to check whether it's the primitive value of the given value.

Return type

Lees<Value>

The return type is a boolean resulting from its statement indicating the value is the Less object that takes the generic type variable Value.

Returns

The return value is a boolean indicating whether the given value is the Less instance of any or given primitive value.

Example usage

// Example usage.
import { Less } from '@angular-package/range';

// Define constant `id`.
const id = 390;

// Returns Less {390} of Less<390>.
const id390 = Less.create(id);

// Returns `true`.
Less.isLess(id390);

// Returns `false`.
Less.isLess(id390, 381);

// Returns `true`.
Less.isLess(id390, 390);
