cluedin-widget/iso/validation/ises/empty.js

This project contains all the pages needed for browsing entities and searching them. The aim is to replace the CluedIn.Webapp project with this one when all the pages ( including the Admin page ) will be ported to REACT.

var type = require( "../type" );

module.exports = function( value ) {
    var empty = false;

    if ( type( value ) === "null" || type( value ) === "undefined" ) {
        empty = true;
    } else if ( type( value ) === "object" ) {
        empty = Object.keys( value ).length === 0;
    } else if ( type( value ) === "boolean" ) {
        empty = value === false;
    } else if ( type( value ) === "number" ) {
        empty = value === 0 || value === -1;
    } else if ( type( value ) === "array" || type( value ) === "string" ) {
        empty = value.length === 0;
    }

    return empty;
