h5(class="border-bottom pb-2 fw-bold") Statements
p Statements in Uartix are instructions that perform actions. They can control the flow of execution, declare variables, or perform expressions.
br

b(class="pb-2") Break Statement
p The break statement exits the nearest enclosing loop.

div(class="bg-primary w-100 mt-2")
p(class="text-white m-0 ms-2") example_22.utx
code(class="text-dark")
pre(class="border border-primary p-2")
| <span class="text-success"><i># Break loop if i is 5.</i></span>
|
| <span class="text-primary">loop</span>(i = 0; i &lt; 10; i = i + 1) {
| <span class="text-primary">if</span>(i == 5) {
| <span class="text-primary">break</span>;
| };
|
| <span class="text-primary">render</span> i + <span class="text-warning">&quot;\r\n&quot;;
| };
br

b(class="pb-2") Continue Statement
p The continue statement skips the current iteration of the nearest enclosing loop and proceeds with the next iteration.

div(class="bg-primary w-100 mt-2")
p(class="text-white m-0 ms-2") example_23.utx
code(class="text-dark")
pre(class="border border-primary p-2")
| <span class="text-success"><i># Skip loop iteration if i is even number.</i></span>
|
| <span class="text-primary">loop</span>(i = 0; i &lt; 10; i = i + 1) {
| <span class="text-primary">if</span>(i % 2 == 0) {
| <span class="text-primary">continue</span>;
| };
|
| <span class="text-primary">render</span> i + <span class="text-warning">&quot;\r\n&quot;;
