Function isEqualWith

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

5.10.1

Example

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

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

const array = ['hello', 'goodbye']
const other = ['hi', 'goodbye']

isEqualWith(array, other, customizer)
// => true
