Javascript – Get kids and props worth in React

In reaction, children it is always one support, Please refer:

function App(props) {
  console.log(Object.keys(props)); // Veja que `children` é uma prop.

; } ReactDOM.render(

Olá, mundo!

, document.querySelector('#app') );

So if you want to access the entire object prop, you should stop restructuring:

function ElementPai(props){
  console.log(props); // <-- Agora você tem as _props_. Sempre teve, aliás. :)

You can still use unstructuring to access some props like you did with that support children, Please refer:

function ElementPai({ children, someOtherProp, andAnotherProp }){

Remember that children It is a support, 🙂

Read this documentation to learn more about the restructuring.

How does Rank I of the Heavy Gunner talent Covering Fire react with melee attacks?

Rank I of the Heavy Gunner Talent Covering Fire is on page 97 of the Lancer Core Book First Edition PDF as follows (focus on mine):

As a quick action, choose a character within the line of sight and range of one of your HEAVY ranged weapons and within 10 spaces: you will be affected until the start of your next turn. If your target moves more than 1 field for the duration, Impaired will be deleted You can attack them in response to a HEAVY-RANGE weapon to do half damage, (heat), or (burning).and then this effect ends. You can carry out this attack at any time during your movement (e.g. wait until you leave the cover).

COVERING FIRE can only affect one character at a time – subsequent uses replace previous ones – and ends immediately if your target damages you.

How p. With 104 of the core book notes under the "Patterns" heading in the "Weapons Tags" section, some weapons affect an area rather than a single target:

Some weapons and systems have special attack patterns: LINE, CONE, BLAST and BURST. These attacks affect all targets in a defined area and require a separate attack roll for each target. The damage is rolled once and the bonus damage is halved if multiple targets are affected.

The section then describes how these 4 types of AoEs work in particular.

How does Covering Fire's response to melee attacks work?

  • First of all, AoE attacks (with heavy ranged weapons) can even be
    made with the Covering Fire reaction?
  • If so, they must be centered (or otherwise focused) on the
    Character selected for covering fire? Or they can be placed in any one
    Configuration as long as the selected character is in the AoE? (Tut
    The answer depends on which AoE pattern the attack must use.)
  • Does the reaction attack affect only the selected character? Or do it
    Impact on other goals in AoE how else? (But if
    affect other AoE targets, take full damage / heat / burn,
    or is it also halved?)

Semantic UI React – The input in dropdown does not allow space

I have a drop-down list of nested text input. After adding onClick={event => event.stopPropagation()} I can select and enter an input for the inputs. However, as soon as I hit the spacebar, the dropdown list closes.

I've worked out adding multiple or closeOnChange={false} for the dropdown, the dropdown remains open, but the onChange the input is not triggered, which means that the white space is not added to the string and effectively results in a noop.

I created a simple pen to illustrate the problem that can be found here.

sharepoint online – SPFx React web part on AfterPropertyPaneChangesApplied

I created a simple web part in React and SPFX for Sharepoint Online. In this web part

weather.tsx has all representations and functions of the web part. in the componentDidMount Function I call the external API function by passing parameters and setState This will render the web part with new values.

public componentDidMount() {
    this.getWeather(this.props.latitude, this.props.longitude, 'si').then((weatherForcast: IWeather) => {
        weatherForcast: weatherForcast

    this.getLocation(this.props.latitude, this.props.longitude).then((location: ILocation) => {
        Locations: location


WeatherWebPart.ts has all the labels and fields of the property window that are checked. I don't make this property area reactive and added onAfterPropertyPaneChangesApplied But I don't know how to call this function in this web part and change the status

react.js – Update the status with React and Websockets

I am working on a reaction app with Websocket. In this app there is a socket event listener that returns three types: add. change, and remove, Certain status updates are performed based on the type of reception.

My question would be based on the code below, I have to mutate it correctly users State because I'm not sure if it will follow the principle of the reaction in terms of updating states.

ws.on("connect", () => {


ws.on("feed", response => {
  const prev = response.old_val;
  const next = response.new_val;
  const type = response.type;
  setUsers(users => {
    let currentUser = (...users);
    let index;
    switch (type) {
      case "add":
        return (...users, next);
      case "change":
        index = users.findIndex(u => ===;
        currentUser(index).name =;
        return currentUser;
      case "remove":
        index = users.findIndex(u => ===;
        currentUser.splice(index, 1);
        return currentUser;
        return currentUser;

Javascript – Submit a form, wait for the information to process, and then render (REACT)

I tried to do it like this …

I added a comment in "else" because TS complains. Some "any" are temporary.

I just want it to process the string received from the form before the result is shown on the screen. Every solution, even if it is completely different from mine, is valid.

import React, { useState } from 'react';
import { useSheetDataContext } from '../../context/SheetDataContext';
import { RouteComponentProps } from '@reach/router';

export function GoalMaker(_: RouteComponentProps) {
  const (formData, setFormData) = useState(());
  const (goal, setGoal) = useState(() => makeGoal(formData));
  const { sheetData } = useSheetDataContext();

  if (sheetData.length === 0) {
    return ;

  function makeGoal(formData: any) {
    if (formData) {
      const goal: Goal() = ();
      const applicators = => applicator.NICK) => {
        return applicatorLessons.forEach((_value, _index, array) => {
          if (array.length === 0) {
            // Aqui dentro vai ocorrer toda a lógica
            return goal;
      } else {
      // Eu travei aqui, porque preciso retornar algo.

  return (

{ any) => `${}: ${value.points} - ${value.type}`)}

setFormData(data)} /> ); }
