Listing 19.06 - Using a while loop with replace - Task 2

Create your own replace function. Move the while loop into your function. The function should accept three arguments: template, placeholder and data.

function replace(template, placeholder, data) {
    var filled = template;

    while (filled.indexOf(placeholder) !== -1) {
        filled = filled.replace(placeholder, data);
    }
}


// test the function

var template = "{{title}} by {{author}}. Follow {{author}} {{social}}";

console.log("Starting replacement...");

console.log(replace(template, "{{author}}", "Oskar"));

console.log("...replacement finished.");
