Comparison operators
We created a variable to which the password length was written. Use it to assign the correct color to the bar. If the password is less than or equal to 5 characters in length, then the bar should be red.
We have already worked with the more than comparison operator. JavaScript also has other comparison operators:
1 < 2; // "Less than" operator
1 <= 2; // "Less than or equal to" operator
1 >= 2; // "More than or equal to" operatorNote that the “less than or equal to” and “more than or equal to” operators are indicated using two characters: an angle bracket and an equal sign. These operators work the same way as in mathematics. For example, the “less than or equal to” operator will return true if the number on the left is less than the number on the right or if the numbers are equal.
If the password length is less than or equal to 5 characters, the bar under the input field should turn red. Add a conditional statement inside the oninput handler and, if the condition is true, assign a red background color to the bar.
if (passLength <= 5) {
securityBar.style.backgroundColor = 'red';

Thanks! We’ll fix everything at once!

Console
- On line 17, add a conditional statement. Specify
passLength <= 5as a condition. - Change the background color of the
securityBarelement inside the conditional statement to red:securityBar.style.backgroundColor = 'red';. - Start typing the text in the “Password” input field in the mini-browser. Any three characters will suffice.
Please note how the bar under the input field turns red.
