# Conditional `page`
Learn how to set a conditional breakpoint.
## The problem
```
```
## What you need to know
Often you only want to break when your app is at a certain state. The following code creates 2000 random numbers:
```
function getValue(i){
return Math.random() * i;
}
var arr = [];
for(var i = 0; i < 2000; i++) {
var value = getValue(i);
arr.push(value)
}
```
Chrome lets you add conditional breakpoints that break when an expression evaluates to *truthy*. Right click the line number you’d like to break on and enter the expression.
## The solution
Click to see the answer
The answer is `u`.
