I happen to be working on this, too. I can take a look at an article written by someone else that has https://codeshelper.com/a/11.
var str = `<div>{{ name + sex + 'hello!' }}</div>`;
var data = { name: "joker", sex: "male" };
function tmpl(str, data) {
return str.replace(/\{\{([\S\s]+)\}\}/g, (m, p1) =>
p1.split("+").map(item => {
item = item.trim();
var reg = /^['"]([\s\S]+)['"]$/;
return !reg.test(item) ? data[item] : item.replace(reg, "$1");
}) .join('')
);
}
