Misspelling length in a for loop in a function doesn’t throw an exception. Why? [duplicate]

function multiplyAll(arr) {
  let product = 1;

  for (let i = 0; i < arr.lenght; i++) {
    for (let j = 0; j < arr[i].length; j++) {
      product = product * arr[i][j];
      //console.log(product);
    }
  }

  return product;
}

In the first for loop length has been misspelt but the the code doesn’t throw any error and does not even run.

How to iterate loop inside pure HTML table in react native

I am pushing my items in an array (table format) and then I am showing
that array in the table but it gets undefined.

class Invoice extends Component{
        
        state= {
        addItems = [];
        }
        
        template=()=>{
    let items = "";
    let items_array = [];
    
    for(let i=0;i<this.state.addItems.length;i++)
    {
    items = (
    <tr>
    <td></td>
    </tr>
    )
    items_array.push(items);
    }
    
        const html=`
        <html>
        <body>
        <table>
        <thead>
        <tr>
        <th>Item Name</th>
        </tr>
        </thead>
        <tbody>
        ${items_array}
        </tbody>
        </table>
        </body>
        </html>
        
        
        `
    return html;
        }
        
    printToFile = async () => {
      
        const html = this.template();
        const { uri } = await Print.printToFileAsync({
          html,
        });
    }
        
        
        render(){
        return(
        
        <Button onPress={this.printToFile}>Print</Button>
        )
        }
        }

Can anyone figure out what’s wrong with the code.

How API request file should look like in React app? [closed]

I’ve joined a new project and I see that there are many places that duplicate axios request boilerplate code, for example the following file:

export class Api {
  static sendEmail = async (mail: string) => {
    const response = await axios({
      method: 'post',
      url: `${apiUrl}/auth/login`,
      headers: {
        Accept: 'application/json',
        'Content-Type': 'application/json'
      },
      data: {
        email: mail
      }
    });
    return response;
  };
  static getAdminDashboardData = async () => {
    const response = await axios({
      method: 'get',
      url: `${apiUrl}/admin/dashboard`,
      headers: {
        Authorization: `Bearer ${accessToken}`,
        'Content-Type': 'application/json'
      }
    });
    return response;
  };
  static getIndices = async () => {
    const response = await axios({
      method: 'get',
      url: `${apiUrl}/admin/indices`,
      headers: {
        Authorization: `Bearer ${accessToken}`,
        'Content-Type': 'application/json'
      }
    });
    return response;
  };
  static getListHr = async () => {
    const response = await axios({
      method: 'get',
      url: `${apiUrl}/admin/partenaires`,
      headers: {
        Authorization: `Bearer ${accessToken}`,
        'Content-Type': 'application/json'
      }
    });
    return response;
  };
  static getListProvider = async () => {
    const response = await axios({
      method: 'get',
      url: `${apiUrl}/admin/prestataires`,
      headers: {
        Authorization: `Bearer ${accessToken}`,
        'Content-Type': 'application/json'
      }
    });
    return response;
  };
}

So I want to create a common file for all api calls. This is what I came up with so far.

import axios from 'axios';

export default axios.create({
  baseURL: 'http://localhost:8080/api',
  headers: {
    'Content-type': 'application/json'
  }
});

I know this file should be a little more advanced, i.e. filled with more options, so maybe someone can recommend how to structure it.

Auto link word on a page using javascript

The code below is meant to put links in words, but it works only with english words, I would like it to work with arabic words too

The code

    <script>
// <![CDATA[
document.addEventListener("DOMContentLoaded", function(){
   var links = {
      "مغامرات": "https://www.example.com/search/label/%D9%85%D8%BA%D8%A7%D9%85%D8%B1%D8%A7%D8%AA",
      "East": "https://www.example.com/search/label/%D8%AE%D9%8A%D8%A7%D9%84",
   }
   
   var bodi = document.querySelectorAll("body *:not(script)");
   for(var x=0; x<bodi.length; x++){
      var html = bodi[x].innerHTML;
      for(var i in links){
         var re = new RegExp("([\s|&nbsp;]"+i+"(?:(?=[,<.\s])))", "gi");
         var matches = html.match(re);
         if(matches){
            matches = html.match(re)[0].trim();
            html = html.replace(re, function(a){
               return ' <a href="'+links[i]+'">'+a.match(/[A-zÀ-ú]+/)[0].trim()+'</a>';
            });
         }
      }
      bodi[x].innerHTML = html;
   }
});
// ]]>
</script>

Invoke class getters with use of private members

I have a class like this:

export class Test {
  #foo
  #bar

  constructor() {}

  get foo() {
    if (!this.#foo) this.#foo = 1 * 1
    return this.#foo
  }

  get bar() {
    if (!this.#bar) this.#bar = 2 * 2
    return this.#bar
  }
}

I need all the getters results in this class so I want to invoke all of them.
I have tried to invoke them outside the class but there are private members in the class so I get an error:

TypeError: Cannot read private member #foo from an object whose class did not declare it

I have tried to invoke them inside the constructor by looping on Object.getOwnPropertyNames(this) but this don’t invoke the getters.

Is there a way I can invoke them inside the class so the getters can use the private members?

Thanks!

Animate height and max-height on different elements cause a queue of transitions

Codesandbox: https://codesandbox.io/s/gallant-cori-hdj5w?file=/src/App.js

I have this simple component with two animations: the first one on the height (from 0% to 100%) and the second one on the max-height.
I didn’t understand why they works but not at the same time: the second animation seems like waits the first animation to finish before to start.

The expected behaviour is that both the animation start and end together.

What is the problem?

Convert a specific google sheets tab into a pdf

For a project I am currently working on I’m trying to find a way that lets me turn a specific google sheets tab into a pdf using javascript

Exact match multiple words in regex (datatables)

I’m trying to create a regex search in Datatables which matches a user who belongs to all selected groups.

Example:

User A belongs to Delta, Year 6, Year 6 Netball Team

User B belongs to Delta, Year 6 Netball Team

If Delta and Year 6 are selected as filters, only user A should show in the table. The problem I’m having is that both users are showing when these filters are selected. I don’t think the regex is matching exact strings and, after looking through multiple other answers, I don’t seem to be able to get it to do so.

My solution:

if (!this.items.length) {
    table.column(i).search('');
} else {
    let regex = '^';

    this.items.forEach(v => regex += `(?=.*\b${v}\b)`);

    regex += '.*$'

    table.column(i).search(regex, true, false, true)
}

Which results in: ^(?=.*bDeltab)(?=.*bYear 6b).*$

However, as shown, the user belonging to Delta,Year 6 Netball Team is still being returned.

Getting Multiple Distinct Colors

I have a line chart that allows multiple lines to appear on the same chart depending on the items. However, the amount of items is different as it is based on individuals. Therefore, I would need to have get distinct colors for all the items. The users can pick which items to be visible on the chart. Therefore, the amount of colors needed will be increased when the user picking more items to be visible. As the amount of colors increases, each color should be distinct and distinguishable at first but gradually become similar to each other. Would like to know whether there is a library or segment of code to achieve the objective above?

If function is true then do this

I’m trying to figure out how to make this work.

I want the validation function to check if all the user inputs are true, then a message in success ID will show You have successfully created an account. once the submit button is clicked.
