Simplify conditionals<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>If a condition becomes complex, it is advisable to decompose it into simpler subconditions using logical operators such as AND (&amp;&amp;) or OR (||).<\/p>\n<h3><span class=\"ez-toc-section\" id=\"2_Utilizar_bloques_IF_ELSE_anidados\"><\/span>2. Use nested IF ELSE blocks<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>In some cases, it may be necessary to make additional decisions within IF ELSE blocks.

Avoid ambiguities<span class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>Make sure your conditions are clear and easy to understand. Avoid using double negatives or confusing comparisons.
