collection-visit
Advanced tools
Visit a method over the items in an object, or map visit over the objects in an array.
Package description
The collection-visit npm package is designed to provide a simple way to visit and apply functions to elements in an object or array. It allows developers to easily manipulate and handle collections of data by iterating over them and invoking a specified method on each element of the collection.
Visiting objects
This feature allows you to visit a specific path within an object and perform operations on it. In the code sample, the `visit` function is used to log the value at the path 'a.b' within the object.
const visit = require('collection-visit');
const obj = { a: { b: { c: 'd' } } };
visit(obj, 'a.b', console.log); // logs { c: 'd' }Visiting arrays
This feature enables visiting elements within an array and applying a function to each element. The code sample demonstrates visiting each object in the array and logging the 'name' property.
const visit = require('collection-visit');
const arr = [{ name: 'Alice' }, { name: 'Bob' }];
visit(arr, 'name', console.log); // logs 'Alice' and 'Bob'Lodash is a comprehensive toolkit similar to collection-visit but with a broader range of utilities for working with arrays, numbers, objects, strings, etc. It includes functions like _.get and _.set for deep property access similar to what collection-visit offers but with additional capabilities like deep cloning, merging, and more.
Object-visit is similar to collection-visit but is specifically tailored for objects. It allows you to visit and update values at specified paths within an object. It's more specialized compared to collection-visit which handles both arrays and objects.

Install with npm:
$ npm install --save collection-visit
var visit = require('collection-visit');
var ctx = {
data: {},
set: function (key, value) {
if (typeof key === 'object') {
visit(ctx, 'set', key);
} else {
ctx.data[key] = value;
}
}
};
ctx.set('a', 'a');
ctx.set('b', 'b');
ctx.set('c', 'c');
ctx.set({d: {e: 'f'}});
console.log(ctx.data);
//=> {a: 'a', b: 'b', c: 'c', d: { e: 'f' }};
