Benchmark: [Object.entries after fixed] Reduce vs Looping vs Ifs vs Destructuring vs Object.entries vs Single loop vs Single reduce vs Template string vs Template function2

Script Preparation code:

var input = { foo: 'lorem', bar: 'ipsum', baz: null, qux: 'dosol', quz: 'set'}
var reduce = (itemsArray, callback, seed) => {
  let accumulator = seed;
  for (let i = 0; i < itemsArray.length; i += 1) {
    accumulator = callback(accumulator, itemsArray[i], i);
  }
  return accumulator;
};
var allowedKeys = ['foo', 'bar', 'baz'];

function renderAttribute(key, value) {
  return value ? `data-analytics-view-custom-analytics-${key}="${value}"` : '';
}

Tests:

Reduce
const keys = ['foo', 'bar', 'baz']; const setProperty = (acc, key, value) => value ? (acc[key] = value) && acc : acc; const result = keys.reduce((acc, key) => setProperty(acc, key, input[key]), {}); Object.entries(result).map( ([key, value]) => `data-analytics-view-custom-analytics-${key}="${value}"`, ).join(' ')
Looping
const keys = ['foo', 'bar', 'baz']; const setProperty = (acc, key, value) => value ? (acc[key] = value) && acc : acc; const result = reduce( keys, (acc, key) => setProperty(acc, key, input[key]), {} ); Object.entries(result).map( ([key, value]) => `data-analytics-view-custom-analytics-${key}="${value}"`, ).join(' ')
Ifs
const { foo, bar, baz } = input; const result = {}; if (foo) { result.foo = foo; } if (bar) { result.bar = bar; } if (baz) { result.baz = baz; } Object.entries(result).map( ([key, value]) => `data-analytics-view-custom-analytics-${key}="${value}"`, ).join(' ')
Destructuring
const { foo, bar, baz } = input; const result = { foo, bar, baz }; Object.entries(result).map( ([key, value]) => value ? `data-analytics-view-custom-analytics-${key}="${value}"` : '', ).join(' ')
Object.entries
const { foo, bar, baz } = input; const result = Object.entries({ foo, bar, baz }).filter(([key, value]) => value !== null && value !== undefined); result.map( ([key, value]) => `data-analytics-view-custom-analytics-${key}="${value}"`, ).join(' ')
Single loop
reduce( Object.entries(input), (acc, [key, value]) => (~allowedKeys.indexOf(key) && value) ? `${acc} data-analytics-view-custom-analytics-${key}="${value}"` : acc, '' );
Single reduce
Object.entries(input).reduce( (acc, [key, value]) => (~allowedKeys.indexOf(key) && value) ? `${acc} data-analytics-view-custom-analytics-${key}="${value}"` : acc, '' )
Template string
const { foo, bar, baz } = input; const html = ` ${foo ? `data-analytics-view-custom-analytics-foo="${foo}"` : ''} ${bar ? `data-analytics-view-custom-analytics-bar="${bar}"` : ''} ${baz ? `data-analytics-view-custom-analytics-baz="${baz}"` : ''} `
Template function
const { foo, bar, baz } = input; const html = ` ${renderAttribute('foo', foo)} ${renderAttribute('bar', bar)} ${renderAttribute('baz', baz)} `
