I have a very specific question and hopefully someone can lend me a hand here. I'm quite green when it comes to Javascript much more when it comes to NodeJS. I am using lodash 's _.forIn functionality to traverse and add into an object that's inside an array. The whole thing looks something like this: [ { id: 20, keywords:

Javascript/Lodash/Redux - return object with specific id from an object

半世苍凉 提交于 2019-12-10 18:50:04
问题 So lets say we have an object: names: { 0: {"id": 30, name: "Adam"}, 1: {"id": 1, name: "Ben"}, 2: {"id": 15, name: "John"}, ... } and using lodash get function I want to save specific name into constant. const name = _.get(state, ['names', nameId]); I know this will not work because I'm selecting the key of the object not the id. Any idea how to fix it ? Note that I can't normalize the data like use the id as a key of the object because it ruins the order in which those data come from BE. Is

Write a typesafe 'pick' function in typescript

醉酒当歌 提交于 2019-12-10 17:57:39
问题 lodash has the pick function which is used as follows: var object = { 'a': 1, 'b': '2', 'c': 3 }; _.pick(object, ['a', 'c']); // => { 'a': 1, 'c': 3 } I would like to write a type-safe version of this in typescript. Usage of this function should be pick(object, o => o.a, o.b) The goal is not to specify the same keys twice, and at the same time conserve type safety. Is this possible to achieve? 回答1: Sounds like you might be looking for the Pick type. Would something like this work for you?

Partition Javascript array of primitive types into multiple parts

丶灬走出姿态 提交于 2019-12-10 17:47:37
问题 I want to be able to partition an unordered array of primitive types like so: var array = [102,103,104,201,203,204,303,301,302,405,406,408,101]; => newArray = [[101,102,103,104],[201,203,204],[303,301,302],[405,406,408]] The array gets partitioned into segments based upon the first integer. The array would be partitioned based on something similar to this expression: array[i]/100|0 === j; where j could be 1,2,3, or 4. eg. 405/100|0 === 4 // partition into the array starting with 4.
