ES6 Template like strings in ES3 compatible syntax.

String.prototype.template.js

// this is now a module:
// https://github.com/WebReflection/backtick-template#es2015-backticks-for-es3-engines--


var template = require('backtick-template');

// just string
const info = 'template';
`some ${info}` === template('some ${info}', {info});

// passing through a transformer
transform `some ${info}` ===
    template(transform, 'some ${info}', {info});

// using it as String method
String.prototype.template = template.asMethod;

`some ${info}` === 'some ${info}'.template({info});

transform `some ${info}` ===
    'some ${info}'.template(transform, {info});

Is this kinda proposal to get rid of ES6 way? Any luck to discuss it with TC39?

👍
In line# 16 you can write str = this.slice(i, m.index);
instead str = this.slice(i, re.lastIndex - m[0].length);

+1 for @hooblei - there is bad RE which makes } inside embedded expressions impossible.

Has anyone turned this into a module instead of a prototype extend?

I've rewritten the original idea from scratch and covered 100% (let's say it was an excuse to test coveralls but ... hey ...)
