function: isEqualWith


isEqualWith(value: *, other: *, customizer: function): boolean

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]).

Example(s):

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

Params:

Name Type Attribute Description
value The value to compare.
other The other value to compare.
customizer The function to customize comparisons.

Returns:

boolean
