How to use merge - 10 common examples

set (key, value) {
    if (2 === arguments.length) {
      // Create param object and call recursively
      var obj = {};
      obj[key] = value;
      return this.set(obj);
    }

    // key is an object
    merge(this.$_filters, key);

    // notify change of filters
    this.ready(onready.bind(this));

    function onready() {
      this.emit('change', this.get());
    }

    // reload items with updated filters
    this.reload();

    // save current state
    return this.save();
  }

// If it does then retrieve the value of it here or return false
  configMerge = configMergeExists ? config.options['merge-default-rules'] : false;

  // check to see if inline options contains an options property and whether property has a property called merge-default-rules
  optionsMergeExists = (options.options && typeof options.options['merge-default-rules'] !== 'undefined');

  // If it does then retrieve the value of it here or return false
  optionsMerge = optionsMergeExists ? options.options['merge-default-rules'] : false;


  // order of preference is inline options > user config > default config
  // merge-default-rules defaults to true so each step above should merge with the previous. If at any step merge-default-rules is set to
  // false it should skip that steps merge.
  defaults = confHelpers.loadDefaults();
  finalConfig = merge.recursive(defaults, config, options);

  // if merge-default-rules is set to false in user config file then we essentially skip the merging with default rules by overwriting our
  // final rules with the content of our user config otherwise we don't take action here as the default merging has already happened
  if (configMergeExists && !configMerge) {
    finalConfig.rules = config.rules;
  }

  // if merge-default-rules is set to false in inline options we essentially skip the merging with our current rules by overwriting our
  // final rules with the content of our user config otherwise we check to see if merge-default-rules is true OR that we have any inline
  // rules, if we do then we want to merge these into our final ruleset.
  if (optionsMergeExists && !optionsMerge) {
    finalConfig.rules = options.rules;
  }
  else if ((optionsMergeExists && optionsMerge) || options.rules && Object.keys(options.rules).length > 0) {
    finalConfig.rules = merge.recursive(finalConfig.rules, options.rules);
