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 = "Using a while loop with replace by . Follow  ";

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

console.log(replace(template, "", "Oskar"));

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