isEqualWith

_.isEqualWith(customizer, value, other) # Ⓢ [Ⓣ][1] Ⓝ

This method is like _.isEqual except that it accepts customizer which

is invoked to compare values. If customizer returns undefined, comparisons

are handled by the method instead. The customizer is invoked with up to

six arguments: (objValue, othValue [, index|key, object, other, stack]).

Since

4.0.0

Arguments

1. customizer (Function): The function to customize comparisons.
2. value (*): The value to compare.
3. other (*): The other value to compare.

Returns

(boolean): Returns true if the values are equivalent, else false.

Example

function isGreeting(value) {
  return /^h(?:i|ello)$/.test(value);
}

function customizer(objValue, othValue) {
  if (isGreeting(objValue) && isGreeting(othValue)) {
    return true;
  }
}

var array = ['hello', 'goodbye'];
var other = ['hi', 'goodbye'];

_.isEqualWith(customizer, array, other);
// => true
