My function getComboRefer returns is not what i'm expecting;

console.log(getComboRefer(2, 'count')) should return 11 but instead console is printing undefined

comboReferData = 
[
  {wagerType: 1,count: 2},
  {wagerType: 2,count: 11}
]


function getComboRefer(type, option) 
{
    comboReferData.forEach(function(item, i){

        if(item.wagerType === type){
          switch(option) 
          {       
            case 'count':
              return item.count

            case 'wt':
              return

            default:
          }
        }
    });
}

console.log(getComboRefer(2, 'count'))

Can someone explain me why?

Your getComboRefer() function returns nothing: it has no return statement. The one in your .forEach() will just stop the loop execution.

comboReferData = [
  {wagerType: 1,count: 2},
  {wagerType: 2,count: 11}
]

function getComboRefer(type, option) {
      let result;

      comboReferData.forEach(function(item, i) {
        if (item.wagerType === type) {
          result = item[option];
        }
      });
      
      return result;
    }

console.log(getComboRefer(2, 'count'))

Some Tips, Tricks, and Common Errors — How to Think Like a , But if the function should return a value, make sure all execution paths do It would be wrong to split the string into words unless we were asked whether the� If num_chars is greater than the length of text, the RIGHT Excel function returns the complete text. The RIGHT function in excel should not be used with numbers. Though it can perform the same operation on digits as it does with text, it returns wrong values with number formatted text. How To Use RIGHT Function in Excel?

You could take find and return the wanted property.

function getComboRefer(type, option) {
    return (comboReferData.find(o => o.wagerType === type) || {})[option];
}

var comboReferData = [{ wagerType: 1, count: 2 }, { wagerType: 2, count: 11 }];

console.log(getComboRefer(2, 'count'))

Why do Python functions return None?, We had this code that turned out to be wrong because we'd forgotten that list. append() does not (I.e. there is no return value from the function. Therefore, if you attempt use the Left, Mid or Right function on a date, the function will return the start, mid or end characters of the number that represents that date. For example, 01/01/1980 is represented by the number 29221, so applying the Right function to a cell containing the date 01/01/1980 (and requesting that 4 characters be returned) would result in a returned value of "9221".

First of all forEach loop doesn't return any value, also you didn't return any value from your function, if you want to return value you can use map, also you should return the value from your function:

comboReferData = [
  {wagerType: 1,count: 2},
  {wagerType: 2,count: 11}
]

function getComboRefer(type, option) {
      const res = comboReferData.map(function(item, i){
        if(item.wagerType === type){
          switch(option) {
            case 'count':
              return item.count
            case 'wt':
              return
            default:
          }
        }
      });
    return res

    }


console.log(getComboRefer(2, 'count'))

function return wrong output - MATLAB Answers, I have a function called maxmin3. When I call it, it gives me the wrong output. But when I get rid of the function definition and make it like a normal script file,� The RIGHT function always returns a text string, even though it contains digits and looks like a number. This is important if we wish to use the result of the function within other functions or formulas. Using the VALUE function, we can ensure the number format is kept and the result is not converted to text.

instead of using foreach method you can try to use for loop as below

function getComboRefer(type, option) {
   for(let i=0;i<comboReferData.length;i++){
       let item=comboReferData[i];
       if(item.wagerType === type){
        switch(option) {
          case 'count':
            return item.count
          case 'wt':
            return
          default:
        }
      }
   }
   return null;
}

Function return values, Some functions don't return a significant value, but others do. You've already met return values a number of times, although you may not have thought It is generally a good idea to check that any necessary parameters are� In a function returning (possibly cv-qualified) void, the return statement with expression can be used, if the expression type is (possibly cv-qualified) void. The copy-initialization of the result of the function call is sequenced-before the destruction of all temporaries at the end of expression , which, in turn, is sequenced-before the destruction of local variables of the block enclosing

As you are passing a function to forEach, your return statement belongs to that function. Its not the return statement of your getComboRefer function.

12.5. Returning a value from a function — Foundations of Python , Not only can you pass a parameter value into a function, a function can also Since line 6 uses the return value as the right hand side of an assignment� I would like to use the right function (or any other function if feasible) in order to take this empty space out of the text in the cell (however the tricky part is that the formula should work only if there is a space in the end of the text, if it is a symbol it should not change the text. Also the formula should not delete other empty spaces within the text, only the empty space at the end

6.2. Functions that Return Values — How to Think like a Computer , Functions that return values are sometimes called fruitful functions. In many other func-2-1: What is wrong with the following function definition: def addEm(x, y,� More precisely, the RIGHT function allows you to get the last (further to the right) characters in a text string. You decide, and tell Excel, how many characters it should return. The syntax of the RIGHT function is, basically, the same as that of the LEFT function: “RIGHT(text,num_chars)”, where:

What's the difference between the print and the return functions , First thing to note is that return and print are statements, not functions, but that is it be right to say that return essentially tells us the output of the functions whilst � I had an issue with index match but the problem was not listed here. I used a cell reference as my lookup value, it worked in all other cases but for some reason, when I used the actual value, the formula worked.. but when I used a reference cell in the formula (which had the exact same value) it did not work. I still cant figure out why. Reply

Return statement, Languages with an explicit return statement create the possibility of multiple return statements in the same function. Whether or not that is a good thing is� Use the RIGHT function when you want to extract characters starting at the right side of text. num_chars is optional and defaults to 1. RIGHT will extract digits from numbers as well. Number formatting is not part of a and will not be extracted or counted.

  • You return from the forEach callback, not getComboRefer.
