if statement inside string template literals and lit-html.

template.js

//a quick example of how to use actual 'if' statements inside template literals,
//without using ternary operator. Sometimes this is cleaner if you have complex conditionals or nested conditionals.
//data param is passed in via render(template(data), this) - if not using lit-html, could be any function
template = (data) => html` 
    <div id="job_edit" class="modal">
        <div class="modal-content">
            ${
                //we're just going to wrap an anonymous inline function here and then call it with some data
                (job => { //job here, is just an example, it could be anything, it's passed in below in (data.job)
                    if(job) 
                        return html`<h4>Edit Job</h4>`
                    else
                        return html`<h4>Create Job</h4>`
                })(data.job) //call the anonymous inline with the data we care about
            }
        </div>
    </div>
