Hi {{ \${first_name} | default: 'Valued User' }}, thanks for using the App!
-- note that the example had an extra right bracket:
{{\${first_name} | capitalize | strip | default: 'friend'}}}
{{\${first_name} | capitalize | strip | default: 'friend'}}
-- Suggested more localization friendly method instead of "default": --
Hello {% if \${first_name} == "" %}friend{% else %}{{\${first_name}| capitalize | strip}}

// Reset `lastIndex` if this regex is defined globally
// regex.lastIndex = 0;
let m;
while ((m = regex.exec(str)) !== null) {
// This is necessary to avoid infinite loops with zero-width matches
if (m.index === regex.lastIndex) {
regex.lastIndex++;
}
// The result can be accessed through the `m`-variable.
m.forEach((match, groupIndex) => {
console.log(`Found match, group ${groupIndex}: ${match}`);
});
