Uses `for-each-break` to create break and return emulation as if it was a regular `for` or `while` loop. To simulate break return `BREAK` or `RETURN`, to simulate `return` return `BREAK(value)` or `RETURN(value)` both are equivalent but the one communicating the right intent should be used. The functions assume `this` is an array or object so they should be invoked with `.call(arrayLike, callback)` defines: * `eachProp` - invoke callback for each own property, order looping over the properties is not defined * `hasOwnProperties` - true if has any own non-undefined properties * `arrayObjectKeys` - collect array like indexed values and keys from both objects and arrays returns `{ arrayValues: [], objectKeys: [], }` where `arrayValues` is an array of property values for integer>=0 props and objectKeys other own property keys * `eachDir` - property looping where direction is provided as an argument * `each` - invoke callback for each own property, first array index like properties in increasing index order then own properties in natural sort order * `eachRight` - invoke callback for each own property, first own properties in reverse natural sort order then array index like properties in decreasing index order * `cloneArrayObject` - clone array or object with all own properties * `deleteItems` - delete items in an array, arguments are deep flattened * `arrayLength` - return array like length for an object or array * `deepClone` - deep clone array or object * `mergeDefaults` - merge defaults into object properties * `copyFiltered` - copy properties chosen by filter * `copyFilteredNot` - copy properties not chosen by filter * `objFiltered` - filter for object/array own properties, not only integer indexed properties, result is object/array depending on this for call * `objFilter` - filter for object/array own properties, not only integer indexed properties, result is an array * `objMapped` - object map for object/array own properties, not only integer indexed properties, result is object/array depending on this for call * `objMap` - map for object/array own properties, not only integer indexed properties, result is array * `objSome` - some for object/array own properties * `objEvery` - some for object/array own properties * `objReduceIterated` - reduce taking iteration functions and callback * `objReduce` - reduce for object/array own properties, order of looping over properties not defined * `objReduceLeft` - reduce for object/array own properties, order of looping over properties is same as `each` * `objReduceRight` - reduce for object/array own properties, order of looping over properties same as `eachRight` For convenience `for-each-break` module's exports are re-exported: * `BREAK` - used to break or return from loop, using `BREAK` to break out of loop is preferred since it communicates clear intention * `RETURN` - used to break or return from loop, using `RETURN` to break out of loop and return a value is preferred since it communicates clear intention * `filter` - use to filter array like object, with early break or return: `filter.call(arrayLike, callback, thisArg)` * `forEach` - use to loop over array like object: `forEach.call(arrayLike, callback, thisArg, defaultReturn)` * `map` - use to map array like object, with early break or return: `map.call(arrayLike, callback, thisArg)` * `filterRight` - use to filter array like object in reverse, with early break or return: `filter.call(arrayLike, callback, thisArg)` * `forEachRight` - use to loop over array like object in reverse: `forEach.call(arrayLike, callback, thisArg, defaultReturn)` * `mapRight` - use to map array like object in reverse, with early break or return: `map.call(arrayLike, callback, thisArg)` ## Install Use [npm](https://npmjs.com/) to install. ``` npm install obj-each-break --save ``` ## Usage [![NPM](https://nodei.co/npm/obj-each-break.png)](https://www.npmjs.com/package/obj-each-break) ## License MIT, see [LICENSE.md](https://github.com/vsch/obj-each-break/blob/master/LICENSE.md) for details. --- _Source: https://npm.io/package/obj-each-break · Machine-readable twin of the npm.io package page.
