some (, isPositive ) // true every(array, callback, context)Ĭheck if all of the items in the array match the predicate, you need to pass a predicate function and an optional context. This can be handy in replicating _.findWhere, which slapdash doesn't implement. Returns a function which accepts an object as a parameter, and returns true if every property of the object matchAgainst exists in object and is strictly equivalent ( =). Returns true if and only if every property of the object matchAgainst exists in object and is strictly equivalent ( =). If there's demand for an objectFilter method, raise an issue/PR. If context is supplied, it will be passed to callback as this. Returns a new array containing the items in array for which predicate returns true. This only supports arrays, not objects.Returns a new array, containing the result of calling each member of array's methodName method. This only supports objects, not arrays.
This implements the object behavior of lodash's reduce method. ObjectReduce(object, callback, initialValue) Returns a new array, containing the key attribute from each member of array. There is no objectFind, as it's really not that useful.
Otherwise, this provides its own implementation. Lodash's default behavior returns an array of mapped-over values - to get an array back from objectMap, use objectMap.asArray(.) Notes Returns a new object, with the same keys, but with the values passed through callback. For string support, use pluck.īehaves like map, but operates on the values of an object. This is similar to passing an object to lodash's each method. Iterates over the properties of object, calling callback on each.
Returning false will not halt execution of this loop, unlike lodash.Negative values are supported for start/ end. Returns a subset of array, from the index start to the index end. This is a featurefill around Object.values. Returns the own property values of object. This is a featurefill around Object.keys. This does not support the optional callback and context methods from lodash.sources)ĭepending on the browser (and/or bad polyfills), this is either Object.assign or an equivalent featurefill. This returns a wrapper function around method, passing context as this, and optionally passing one or more arguments. For most common use cases involving a non-function callback, an alternative will be provided.ĪPI Reference bind(method, context, arguments.) Callbacks supplied to these methods may only be functions.Each of lodash's collection methods will be implemented to support arrays only, with an object-specific version provided separately. Slapdash's 'collection' methods are split into two sets - array and object.Unless the operand in question is declared near to where it is used (or there is an assertion/invariant to validate the type), it can be difficult to determine what type it actually is.

By not implementing the full lodash/underscore API, a lot of cruft can be removed.So, Slapdash featurefills missing native methods without touching any prototypes. I mean, it doesn't even have Object.keys!. Maybe you're writing script for deployment on 3rd party sites - maybe that 3rd party decides to override Function::bind with something incompatible? Don't worry. We don't all have control over our execution environment.IE8/9 are a distant memory for most web developers, but unfortunately for some of us they remain a waking nightmare.Slapdash's prodigious speed allows him to do everything quickly-which he likes, because anything else would require effort. Be compatible with Internet Explorer 8 and up.Slapdash is a lightweight JavaScript utility belt, inspired heavily by
