不。 程式化和文字是对立的（除了你在编译器的领域）。

No. "programmatically" and "literal" are antithetic (except you are in the realms of compilers).

模板字符串应该更好地被命名为<内插字符串文字等等。请 不要将其与模板混淆 。如果要使用动态创建的模板字符串，请使用您选择的模板引擎。

Template strings should better have been named interpolated string literals or so. Please do not confuse them with templates. If you want to use dynamically created strings for templates, use a template engine of your choice.

当然，模板文字可能有助于实现这些，您可能会除了简单的东西，如

Of course template literals might help with the implementation of such, and you might get away with something simple as

function assemble(literal, params) {
    return new Function(params, "return `"+literal+"`;"); // TODO: Proper escaping
//             ^^^^^^^^ working in real ES6 environments only, of course
}
var template = assemble("Hello, my name is ${name}", "name");
template("Chaim"); // Hello, my name is Chaim
