Example

The following example demonstrates the usage of the random() method in CoffeeScript. Save this code in a file with name math_random.coffee.

value = Math.random()
console.log "The first number is : " + value 
         
value = Math.random()
console.log "The second number is : " + value 
        
value = Math.random()
console.log "The third number is : " + value

Open the command prompt and compile the .coffee file as shown below.

c:\> coffee -c math_random.coffee

On compiling, it gives you the following JavaScript.

// Generated by CoffeeScript 1.10.0
(function() {
  var value;

  value = Math.random();

  console.log("The first number is : " + value);

  value = Math.random();

  console.log("The second number is : " + value);

  value = Math.random();

  console.log("The third number is : " + value);


}).call(this);

Now, open the command prompt again, and run the CoffeeScript file as shown below.

c:\> coffee math_tan.coffee

On executing, the CoffeeScript file produces the following output.

The first number is : 0.44820353598333895
