Can below code be simplify?

	var index = 0;
	var temp = "12345";
	temp = temp.slice(0,index)+ "H" + temp.slice(index);
	console.log("Temp:" + temp);

I try searching and wonder whether JQuery got any method to insert string by index....

Example.

var temp = temp.append(0, "H");...

Thanks

jQuery's core functions have little to do with things to do like string manipulation, and are mostly only concerned with client-side functions like events, DOM manipulation, etc. There may be someone who has built some utility methods as an extension to jQuery, but that is not what jQuery is good for, so the useful in regards to jQuery of such a method is questionable.

Why don't you develop a few of your own utility functions for future use? The example you gave could be accomplished with the String.prototype. jQuery doesn't extend native objects for philosophical reasons, so if there is a method built in jQuery or a plugin, its syntax will be different, and will always be chained to the jQuery global object ($ or jQuery).
