Question

i am tired of writing this:

string_needed=”prefix…..” + topic + “suffix….” + name + “testing”;

i would think someone might have done something about this by now 😉

Answer 1

ES6 Update:

ES6 added template strings, which use backticks (`) instead of single or double quotes. In a template string, you can use the ${} syntax to add expressions. Using your example, it would be:

string_needed = `prefix.....${topic}suffix....${name}testing`

Original answer:

Sorry 🙁

I like to take advantage of Array.join:

["prefix ....", topic, "suffix....", name, "testing"].join("")

or use String.concat

String.concat("a", 2, "c")

or you could write your own concatenate function:

var concat = function(/* args */) {
    /*
     * Something involving a loop through arguments
     */
}

or use a 3rd-party sprintf function, such as http://www.diveintojavascript.com/projects/javascript-sprintf
