A tool for working with JavaScript platforms agnostically

var api = {}

api.platform = getPlatform()
api.isServer = !!~['node'].indexOf(api.platform)
api.isClient = !!~['browser'].indexOf(api.platform)
api.GLOBE = api.isServer ? GLOBAL : window
/*  Simple friendly alias since capitalization
    is not consistent amonst platforms...
    window GLOBAL etc. */
api.globe = api.GLOBE



platformExport(api, 'plat')
