6 Golden Rules To Write Clean Code

Larry — Sat, 10 May 2025 02:48:06 +0000

If you want to write clean code, learn these 6 rules:

Separation of Concerns (SOC)
=> Break down a complex program into smaller units.
Document Your Code (DYC)
=> Write code for your future self and others.
Don't Repeat Yourself (DRY)
=> Don't waste time writing the same code again.
Keep It Simple, Stupid (KISS)
=> Simple is hard, but better.
Test Driven Development (TDD)
=> Write a failing test first and code to make the test pass.
You Ain't Gonna Need It (YAGNI)
=> Build only essential features.

customize your zsh

Larry — Thu, 07 Oct 2021 17:53:05 +0000

When someone wants to customize own mac zsh terminal and use color for each text also wants to show git branch name then you can add below code in your .zshrc

# Git branch in prompt.
parse_git_branch() {
    git branch 2> /dev/null | sed -n -e 's/^\* \(.*\)/[\1]/p'
}

setopt PROMPT_SUBST
export PROMPT='%F{cyan}%n@%M:~ %F{yellow}%. %F{green}$(parse_git_branch)%f %F{normal}$%f '

Here,
%n => mac username
%M => mac computer name
%. => current folder name
$(parse_git_branch)%f => git branch name (if working in git repo)

How to remove the falsy value attribute from object

Larry — Thu, 08 Apr 2021 13:47:00 +0000

Sometimes we want to remove null, empty, undefined, false value attribute from an object. we can do this using the below method.

const removeFalsyElement = object => {
  const newObject = {};
  Object.keys(object).forEach(key => {
    if (object[key]) {
      newObject[key] = object[key];
    }
  });
  return newObject;
};

assume my object like this

const myObject = {
  withValue: "have some value",
  withNumber: 1234,
  nullValue: null,
  undefinedValue: undefined,
  emptyValue: "",
  falseValue: false
};

and want to return those attribute which has actual value.
usage

console.log(removeFalsyElement(myObject));
// output: Object { withValue: "have some value", withNumber: 1234 }

use javascript Date()

Larry — Wed, 24 Mar 2021 05:32:05 +0000

How do we get current date using Date() function?

var date = new Date();
console.log("Today's date is:", date);

// Today's date is: Tue Mar 23 2021 23:14:47 GMT+0600 (Bangladesh Standard Time)

Here output will give with GMT and timezone.
If we want to grab specific value then we need to use some method like getMonth(), getDate(), getFullYear() etc...

console.log("Today's date is " + date.getMonth() + "/" + date.getDate() + "/" + date.getFullYear());
// Today's date is 2/23/2021

Here, getMonth() return month index and it is start with 0 that why month says 2 instead of 3 . So, if we get correct month, we have to add 1 with the method.
getDate() return current date.
getFullYear() return 4 digits of current year.

console.log("Today's date is " + (date.getMonth() + 1) + "/" + date.getDate() + "/" + date.getFullYear());
// Today's date is 3/23/2021
