6.1 Comparison Operators<\/strong><\/h3>\n

In\u00a0lesson 5, we have learned basic arithmetic operations in JavaScript,\u00a0in\u00a0this\u00a0lesson, we\u00a0will introduce the comparison operators. Using comparison operators, we can\u00a0write decision-making procedures.\u00a0If a certain condition is met, JavaScript will execute an action, otherwise, there is no action or it will take alternative action. The following Table demonstrates the comparison operators.<\/p>\n
