Debugging with Console & DevTools

Conditional breakpoints provide targeted debugging: 1) They pause execution only when a specified condition evaluates to true, 2) This allows focusing on specific scenarios or edge cases, 3) For loops or frequently called functions, they prevent breaking on every iteration/call, 4) They're set by right-clicking a line number and entering a JavaScript expression, 5) The condition can use any variables in scope at the breakpoint location, 6) This is invaluable for debugging issues that only occur with specific values or states, 7) For example, breaking only when a loop counter reaches a specific value or when an object has unexpected properties, 8) This highly selective breaking significantly reduces the time spent manually stepping through code to reach the relevant condition.
