/**
|
||
|
|
* 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]).

|
* @param {*} value The value to compare.
|
||
|
|
* @param {*} other The other value to compare.
|
||
|
|
* @param {Function} [customizer] The function to customize comparisons.
|
||
|
|
* @returns {boolean} Returns `true` if the values are equivalent, else `false`.
|

|
* @example
|
||
|
|
*
|
||
|
|
* function isGreeting(value) {
