const variables = {

    string = string.replace(new RegExp(`{{${curMatch[1]}}}`, 'g'), found[trimd]);

const output = mapVariables(variables, '{{ name }} is a {{job}} at MyZone Media.' );

console.log( output );

// Output if all vars are found
// Bican Marian Valeriu is a WordPress Developer at MyZone Media.

// Output if just some of the vars are found
// Bican Marian Valeriu is a {{job}} at MyZone Media.
