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>
`;

Simplified version:

const template = data => `
    <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 ? `<h4>Edit Job</h4>` : `<h4>Create Job</h4>` )(data.job) //call the anonymous inline with the data we care about
            }
        </div>
    </div>
`;
console.info( template( { job: false } ) );

@franz-josef-kaiser, thanks for the example, but as I mention in the comments:

The whole point of this gist is to demonstrate how to use an 'if' statement without the ternary operator. This is especially useful if you have a lot of if/else conditions.

@claytongulick I overread that. Anyway, you can still remove the else as you return in the if anyway. Whatever passes the first condition is executed, no matter what. Makes it a bit easier to read and understand when there's no conditional logic wrapped around the command.
