nl_tokens: Creates a clone of value . If deep is true nested objects will also be cloned otherwise they will be assigned by reference . If a callback is provided it will be executed to produce the cloned values . If the callback returns undefined cloning will be handled by the method instead . The callback is bound to thisArg and invoked with one argument ; ( value ) .
pl_tokens: function clone ( <mask> , deep , callback , thisArg ) { // allows working with "Collections" methods without using their `index` // and `collection` arguments for `deep` and `callback` if ( typeof deep != 'boolean' && deep != null ) { thisArg = callback ; callback = deep ; deep = false ; } return baseClone ( value , deep , typeof callback == 'function' && baseCreateCallback ( callback , thisArg , 1 ) ) ; }
