A lib to make the complex and daily used functions easy to use.

var fnError = require('./error');

module.exports = {
    storeCheck: function () {
        try {
            localStorage.setItem('lst', +new Date());

            localStorage.removeItem('lst');
        } catch (e) {
            fnError('Local storage is not available in your browser');
        }
    },
    notNullCheck: function(value, text) {
        if(value === undefined || value === '' || value === null) {
            fnError(`${text} is mandatory!`);
        }
    },
    toStrCheck: function(value) {
        if(typeof value === 'object') {
            fnError('Invalid input: object, array!');
        }
    },
    isArrayCheck: function(input) {
        if(!(input instanceof Array)) {

        }
    },
    notObjectCheck: function(input) {
        if(!input.every(function(i){
            return i === null || typeof i !== 'object';
        })){
