Question

What improvements can I make to enhance my method?

I have a block of code that I'm looking to clean up and streamline for better efficiency.

My main goal is to remove the multiple return statements within the method.

Any suggestions on how I might refactor this code? Are there any design patterns that could be helpful in this situation? Your advice is greatly appreciated. Thank you!

class Test{    
          private client;
          private concreteMixer;
          constructor(client, concreteMixer){
            this.client = client;
            this.concreteMixer = concreteMixer;
          }

          public method(){
            let form = new Form();
            if(form.isSubmitted()){
              if(form.isValid()){

                let field = form.getField();
                let infoField = this.client.testField(field);
                if(!infoField){
                  form.setError('This is not a valid field');
                  return form;
                }

                let coffee = this.concreteMixer.makeСoffee();
                //two days have passed
                if(!coffee){
                  form.setError('I am craving coffee');
                  return form;
                }

                this.concreteMixer.pourInThermosBottle();
                //two days have passed

                return coffee;
              }
            }

            return form;
          }
        }

Yes, I agree with that approach

    /**
     * Exploring a sample class with comments
     */
    class Test {
      /**
       * Storing the client information
       */
      protected client;

      /**
       * Handling the concrete mixer object
       */
      protected concreteMixer;

      /**
       * Initializing the class with client and concreteMixer parameters
       */
      constructor(client, concreteMixer) {
        this.client = client;

        this.concreteMixer = concreteMixer;
      }

      /**
       * A method to execute certain operations
       */
      public method() {
        const form = new Form();

        // Checking if form submission is valid
        if (!form.isSubmitted() || !form.isValid()) {
          return form;
        }

        // Retrieving field data from form
        const field = form.getField();

        // Requesting information related to field from the client
        const infoField = this.client.testField(field);

        // Handling error scenarios when field information is missing
        if (!infoField) {
          form.setError(ERROR_CODE_01);

          return form;
        }

        // Making coffee using concrete mixer
        const coffee = this.concreteMixer.makeСoffee();

        // Handling scenario when coffee cannot be made
        if (!coffee) {
          form.setError(ERROR_CODE_02);

          return form;
        }

        // Pouring coffee into thermos bottle
        this.concreteMixer.pourInThermosBottle();

        return coffee;
      }
    }

A tip for efficient coding: replacing let with const for variables that do not change can improve code clarity.

Streamlining conditional statements by early returning in case of negative conditions rather than nesting multiple lines of code.

Utilizing error codes instead of plain text messages for better programmatic handling of errors.

Including descriptive comments within your code to explain its functionality and make it easier to comprehend for others or future reference.

Switching from private to protected for improved flexibility in potential inheritance scenarios without needing further modifications.
