                What can you do with ES6 string template literals?

    Motivation


expression-oriented programming one of the great advances of FP
expressions plug together like legos, making more malleable programming experience in-the-small

Examples

Write in an expression-oriented style, scoping variables as locally as possible:


## monocle-mustache-semi.js
// inspired by https://github.com/raganwald/homoiconic/blob/master/2011/11/sans-titre.md#readme
// and by https://groups.google.com/a/dartlang.org/group/misc/browse_thread/thread/611c04100ac17142

// traditional method chaining with combinators:
console.log(range(1, 3)
              .concat(range(4, 6))
              .map(function(x) { return x * x })
              .filter(function(x) { return x % 2 === 0 })
              .reverse());

## combos.js
const ATTRIBUTES = ['A', 'B', 'C', 'D', 'E', 'F'];

// type attribute = 'A' | 'B' | 'C' | 'D' | 'E' | 'F'
// type value = "x" | ""
// type combo = [value]

function combos() {
    return combosFrom(ATTRIBUTES, 0);
}

## geomean.js
// Calculating the geometric mean in log space avoids overflow when
// working with anything more than very small data sets.
//
// The formula can be calculated with simple algebraic identities:
//
//   n√(Prod^n x_i)
// =   { e^ln(x) = x }
//   n√(Prod^n e^ln(x_i))
// =   { e^a x e^b = e^(a+b) }
//   n√(e^(Sum^n ln(x_i)))

## 1-recursive.js
// Version 1. Simple recursive function. Blows the stack for large nodes.
function replace(node, from, to) {
    switch (node.type) {
      case IF:
        return {
            type: IF,
            test: replace(node.test, from, to),
            then: replace(node.then, from, to),
            else: replace(node.else, from, to)
        };

## 1-import-meta.js
// import default export
import.default("Spinner").then(Spinner => {
  widget.appendChild(new Spinner(...))
});

// import namespace object
import.namespace("fs").then(fs => {
  fs.readFile(...)
});
