Everytime the bot chooses rock


#1

var userChoice = prompt("Do you choose rock, paper or scissors?");
var computerChoice = Math.random()
console.log(computerChoice);
if (computerChoice = 0,0.33) {
computerChoice = "rock";
} else if (compterChoice = 0.34,66) {
computerChoice = "paper";
} else {
computerChoice = "scissors";
}
console.log(computerChoice);

This is my code , it passes there is one problem though , everytime the bot chooses rock even when it shouldn't. any idea why?

@christianlfonts,

The Math.random() method will deliver a number with a value
in the range of 0_(included)_ upontill 0.9999_(1 excluded)_.

As you will have to divide the number range form 0_(inclusive)_ to 0,9999_(so 1 excluded)_
into 3 equal partitions
we have to use an if else-if else statement.
The if else-if else skeleton looks like:

    if (conditionA) {
               //conditionA is true
                //your code 
     } else if (conditionB) {
               //conditionA is false
               //conditionB is true
              //your code 
    } else {     // <=== !! Takes NO condition-statements !!
               //conditionA is false
               //conditionB is false
              //your code 
    }

following the Instructions the conditions would be:

  1. If computerChoice is between 0 and 0.33, make computerChoice equal to "rock".
    ( 0 <= computerChoice && computerChoice <= 0.33) which we capture at the IF using
    ( computerChoice <= 0.33)

  2. If computerChoice is between 0.34 and 0.66, make computerChoice equal to "paper".
    ( 0.33 < computerChoice && computerChoice < 0.67) which we capture at the ELSE IF as
    ( computerChoice < 0.67 )

  3. If computerChoice is between 0.67 and 1, make computerChoice equal to "scissors".
    ( 0.67 <= computerChoice && computerChoice < 1) , you reached the ELSE level
    you can asume that computerChoice is greater equal to 0.67,
    the ELSE does NOT take a condition, just write your code.

Ok thank you it worked , so by adding a && and repeating computerChoice is a way of saying inbetween these two numbers. Thank you so much I was wondering how it worked.
