Cypress | Cant change variable inside each loop

OK, So, I have this code:

Cypress.Commands.add ('MethodName', (argument) => {

    var Fails = 0

    cy.get('anything').each(Id => {
        if (blablabla) {
        Fails += 1
            cy.log("Inside the each: " + Fails) //prints 1
    }
    })
    cy.log("Outside the each: " + Fails) //prints 0
 
});

I want to test each item and if a condition is wrong, I want to add 1 to the variable "Fails".

Then, in the end, if Fails is 0, then there are no errors, and I want it to log the message "NO FAILS". The problem is , even if the variable changes to 1 inside the EACH, when its outside, it comes back to 0.

This is so frustrating to me, because Im used to write C# code and in C#, that would work, since the declaration of the variable is outside the each.

What do you guys suggest?

JavaScript runs asynchronously which means that your codes doesn't run in sequence. So what's happening in your case is Outside the each: is executing first and after that Inside the each: is being executed. To make sure that Outside each runs after inside each, you have to use then().

Cypress.Commands.add('MethodName', (argument) => {
   var Fails = 0
   cy.get('anything').each(Id => {
      if (blablabla) {
         Fails += 1
         cy.log("Inside the each: " + Fails)
      }
   }).then(() => {
      cy.log("Outside the each: " + Fails)
   })
})
