I am currently working on crafting a JavaScript algorithm, however, I am faced with the task of transforming

Currently, I am in the process of developing a new JavaScript algorithm named jBam (JavaScript Browser Algorithm Module). This algorithm is designed to provide a straightforward method for detecting a browser and its version. My primary objective is to enable users to implement this functionality with ease by using the library in the following manner:

if(IE & version lessThan 9) {
    // Execute code specific to IE versions 8 and below
}

I have made significant progress in the development phase. I am now able to write:

if(browser == IE & version < 9)

Therefore, my main query involves the possibility of establishing a variable for lessThan and assigning it the value of the symbol <. While I initially attempted the most common approach (var lessThan = <), I quickly realized that this solution was overly optimistic and simplistic. As we are all aware, nothing is ever too easy. Are there any alternative suggestions or perhaps a JavaScript technique that has eluded me?

Answer №1

I concur with @JCOC611's point of view, however, it is conceivable to encapsulate everything into an object and define version as a property within that object. Furthermore, you can introduce a method called lessThan, structuring it in the following manner:

var browserStuff = {
    browser: {
        value: "",
        is: function (comparator) {
            if (browserStuff.browser.value == comparator) {
                return true;
            }
	    return false;
	}
    },
    version: {
        value: "",
        lessThan: function (comparator) {
            if (browserStuff.version.value < comparator) {
                return true;
          	}
	  	return false;
	}
    },
    init: function () {
        // Execute operations to determine the browser and its version
        // Set values for browserStuff.version.value and browserStuff.browser.value
    	delete browserStuff.init;
	}
}.init();

Subsequently, you can utilize it in the following manner:

if (browserStuff.browser.is("IE")) {

}

or

if (browserStuff.version.lessThan("7")) {

}

Please note, additional functionalities like "greater than" comparisons or "not equals" can be incorporated according to requirements. However, I advise against this approach since traditional Javascript operators can achieve similar outcomes with reduced code redundancy. This solution emphasizes readability but does not offer significant advantages.
