If callbackFn never returns a truthy value, find() returns undefined.ĬallbackFn is invoked for every index of the array, not just those with assigned values. find() then returns that element and stops iterating through the array. It calls a provided callbackFn function once for each element in an array in ascending-index order, until callbackFn returns a truthy value.
The find() method is an iterative method. Object.prototype._lookupGetter_() Deprecated.
