Recursively iterates over arrays and objects. The iteration is made using a deep-first algorithm.
``sh`
$ npm install deep-for-each
This library is written in modern JavaScript and is published in both CommonJS and ES module transpiled variants. If you target older browsers please make sure to transpile accordingly.
`js
import deepForEach from 'deep-for-each';
deepForEach({
prop1: 'foo',
prop2: ['foo', 'bar'],
prop3: ['foo', 'foo'],
prop4: {
prop5: 'foo',
prop6: 'bar',
},
}, (value, key, subject, path) => {
// value is the current property valuekey
// is the current property namesubject
// is either an array or an objectpath
// is the iteration path, e.g.: 'prop2[0]' and 'prop4.prop5'
console.log(${path}:, value);`
});
Running the example above will print:
``
prop1: foo
prop2: [ 'foo', 'bar' ]
prop2[0]: foo
prop2[1]: bar
prop3: [ 'foo', 'foo' ]
prop3[0]: foo
prop3[1]: foo
prop4: { prop5: 'foo', prop6: 'bar' }
prop4.prop5: foo
prop4.prop6: bar
`sh``
