Comparison operators in Ember Handlebar files

I have a file ifCond.js, in which I have bunch of helper functions, but I am concerned with mainly two functions log (which logs in values in hbs file) and IMS.ConditionHelper, I am not able to use IMS.ConditionHelper why, I want to use this function for that purpose, how can I do it - any help please? Here is my ifCond.js code:

export default () => {
    var log = function (data) {
        console.log(data);
    }
    var log = Ember.assign(log, {
        print: function (style, message) {
            var template = "";
            style.forEach(function (item) {
                if (typeof item == 'object') {
                    for (var prop in item) {
                        template += prop + ":" + item[prop] + ";";
                    }
                } else {
                    var style = log.styles[item];
                    if (style)
                        for (var prop in style) {
                            template += prop + ":" + style[prop] + ";";
                        }
                }
            })
        },
        styles: {
            title: {
                'font-size': '30px',
            },
            italic: {
                'font-style': 'italic'
            },
            bold: {
                'font-weight': 'bold'
            },
            underline: {
                'text-decoration': 'underline'
            },
            success: {
                'color': '#23aa15'
            },
            error: {
                'color': '#ee3619'
            },
            attention: {
                'color': '#ee339e'
            }
        }
    });

     IMS.ConditionHelper = Ember.Helper.extend({
        compute: function (args) {
            var v1 = args[0],
                operator = args[1],
                v2 = args[2];
            if (v1 === undefined || v2 === undefined) {
                console.warn("Condition BoundHelper received undefined value");
                return false;
            }
            switch (operator) {
                case '!=':
                    return (v1 != v2) ? true : false;
                case '==':
                    return (v1 == v2) ? true : false;
                case '===':
                    return (v1 === v2) ? true : false;
                case '<':
                    return (v1 < v2) ? true : false;
                case '<=':
                    return (v1 <= v2) ? true : false;
                case '>':
                    return (v1 > v2) ? true : false;
                case '>=':
                    return (v1 >= v2) ? true : false;
                case '&&':
                    return (v1 && v2) ? true : false;
                case '||':
                    return (v1 || v2) ? true : false;
                default:
                    return false;
            }
        }
})
}

Any help, I want a conditional operator - any help would be very very helpful - thanks in advance. I am not sure if I am using Ember-cli or Ember webpack but application is working except this ConditionHelper function being called in the Handlebar file - any help would be greatly helpful - thanks in advance
