CoffeeScript is a lightweight programming language that compiles into JavaScript. It provides simple and easy-to-learn syntax, avoiding the complex syntax of JavaScript. CoffeeScript is influenced by JavaScript, Ruby, YAML, Haskell, Perl, and Python and has influenced MoonScript, LiveScript, and JavaScript.
Example: The below example is demonstrating the conversion of CoffeeScript code into JavaScript code:
# Assignment:
number = 89
opposite = false
# Functions:
cube = (A) -> a * a * a
# Conditions:
number = -89 if !opposite
JavaScript is the world's most popular lightweight, interpreted, compiled programming language. It is also known as a scripting language for web pages. It is well-known for the development of web pages, and many non-browser environments also use it. JavaScript can be used for Client-side developments as well as Server-side development
# Assignment:
number = 89;
opposite = false;
# Functions:
cube = function (A) {
return a * a * a;
};
# Conditions:
if (!opposite) {
number = -89;
}
Now let us understand the step procedure of how to convert a CoffeeScript code into JavaScript with the example:
Step 1: Write CoffeeScript code and save the file with evenOrOdd.coffee extension
// Write coffeeScript program to check whether
// given number is even or odd
number = 12
if number % 2 == 0
console.log "number is even"
else
console.log "number is odd"
Step 2: To run the evenOrOdd.coffee file, you need to type the following command :
coffee -c evenOrOdd.coffee
Step 3: After successful compilation of the above evenOrOdd.coffee file, the following JavaScript file will generate.
(function () {
var number;
number = 12;
if (number % 2 === 0) {
console.log("number is even");
} else {
console.log("number is odd");
}
}).call(this);
Output:
number is even
