JavaScript - The Basics

JavaScript - The Basics | Ecency

Learning to code and programming takes time, if someone says coding is easy, you have to rethink it, but all of this is doable, it just takes time.

After a long hiatus and leaving writing syntax and understanding coding logic, now I have to go back to learning from scratch the basics of JavaScript.

I did all this as one of the requirements to get a scholarship to study Back-End Developer which will be taught by Dicoding in September, there are three courses requirements that I must pass, one of which is basic JavaScript.

Many things I re-learned about JavaScript such as a basic introduction to JavaScript, its history and also writing code in JavaScript.

console.log("Hello, World!");

I'm sure everyone has done the same thing when they first learned to code.

Comments

Then I learned about writing comments, both one-line comments and comments in the form of explanatory sentences

// This is a one-line comment, the code below will not run

// console.log("Halo!");

This comment will not be read by the interpreter, another example of writing a comment is as follows;

/* This is a comment with more than one line
Any text that is here will be used as a comment.
*/

I also do the task of calculating if logic to evaluate the score value;

function scoreChecker(score) {
  let result;

  // TODO
  if(score>=90){
  result = 'Selamat! Anda mendapatkan nilai A.';
  }
    
  else if(score>=80 && score<=89){
  result = 'Anda mendapatkan nilai B.';
  }
    
  else if(score>=70 && score<=79){
  result = 'Anda mendapatkan nilai C.'; 
  }
    
  else if(score>=60 && score<=69){
  result = 'Anda mendapatkan nilai D.';
  }
    
  else{
  result = 'Anda mendapatkan nilai E.';
  }


  // Do not delete this
  return result;
}

console.log(scoreChecker(90));

/**
 * Don't delete the code below
 */
module.exports = scoreChecker;

And many more to learn

There are many other basic things that I learned during this course, ranging from Variables, Data types, Operators, Conditional statements, Switch case statements, and loops.

At the end of each section, each participant is provided with a quiz to test the extent of our understanding of the material that has been taught.
