<blockquote><p>The operator with the highest precedence in JavaScript is parentheses (), which are used to change the precedence of other operators. Secondly, the order of operator precedence is: unary operator, exponential operator, multiplication and division operator, addition and subtraction operator, relational operator, logical operator, assignment operator and conditional operator. </p></blockquote> <p><img src="https://img.php.cn/upload/article/202405/09/2024050900422783278.jpg" alt="The operator with the highest precedence in js is" ></p> <p><strong>#What operator has the highest precedence? </strong></p> <p>In JavaScript, the operator with the highest precedence is: </p> <p><strong>Parentheses ()</strong></p> <p>Parentheses are used to change operators precedes any other operator. </p> <p><strong>Operator precedence</strong></p> <p>After the parentheses, the operator precedence is in the following order (from highest to lowest): </p> <ol> <li>Unary operators (such as <code> </code>, <code>-</code>, <code>!</code>)</li> <li>Exponential operators (<code>**</code>)</li> <li>Multiplication and division operators (<code>*</code>, <code>/</code>, <code>%</code>) </li> <li>Addition and subtraction operators (<code> </code>, <code>-</code>) </li> <li> Relational operators (<code>==</code>, <code>!=</code>, <code><</code>,<code>></code>, <code><=</code>, <code>>=</code>) </li> <li>Logical operators (<code>&&</code>, <code>| |</code>、<code>!</code>)</li> <li>Assignment operator(<code>=</code>、<code> =</code>、<code>-=</code>)</li> <li>Conditional operator (<code>?</code>)</li> </ol> <p><strong>Example</strong></p> <p>Here is an example illustrating the practical implementation of operator precedence Application: </p> <pre class="brush:php;toolbar:false"><code class="javascript">let result = 1 + 2 * 3;</code></pre> <p>In this example, the multiplication operator <code>*</code> takes precedence over the addition operator <code> </code> because multiplication has higher precedence. Therefore, <code>2 * 3</code> is first evaluated as 6, and then 6 is added to 1, resulting in 7. </p> <p> If you want to change the priority, you can use parentheses: </p> <pre class="brush:php;toolbar:false"><code class="javascript">let result = (1 + 2) * 3;</code></pre> <p> Now, the parentheses raise the priority of addition above that of multiplication, so <code>1 2</code> First it is evaluated as 3, then 3 is multiplied by 3, and the result is 9. </p>
