String.prototype.replace for Objects

usage

Let's say we have some users:

var data = [
  {name: 'joe', address: '123 Main Lane'},
  {name: 'cecilia', address: '456 Sticks St'},
  ...
]

Let's say we want to preform an in-place modification to some of these values - let's capitalize their names:

var replace = require('object-replace')

replace(data, 'name', function (val) {
  return val.toUpperCase()
})

object-replace is also suitable (in fact, it really shines) for more complex and nested objects. It supports dotnotation selectors with wildcards, powered by object-match.

function signature

In jsig notation:

type Replacer : (val: Value, path: Array<String>) => Value

replace(obj: Object, selectors: String|Array<String>, replacer:Replacer) => Object

Replace modifies the object obj in place, and also returns a reference to it for convenience.

The replacer function is called on each matching value. Its return value is used for the new property value.

installation

$ npm install object-replace
