Is Helper

This is a collection of static helpers that encapsulate basic "determining" functions that are run all the time in JavaScript. Some of these have at one point or another been in the Node engine itself but have moved in and out depending on versioning.

For example...this is quite common:

if (value === undefined or value === null)

The is-helper provides the functionality:

import IsHelper from "@withonevision/is-helper"

if (IsHelper.isNullOrUndefined(value))

The is-helper also adds functionality to certain things like:

import IsHelper from "@withonevision/is-helper"

if (IsHelper.isBoolean(value))

This will not only check if the value is boolean, but will also check if the value is a number equal to 0 for false or 1 for true. It will also check if the value is a string and equal to anything that would be considered "truthy" ("Y/N", "true/false", etc.)

For a full list of functions, see the jsr.io documentation
