When we use an if...else statement inside another if...else statement, we create a nested if...else statement. For example,let marks = 60; // outer if...else statement // student passed if marks 40 or above // otherwise, student failed if (marks >= 40) { // inner if...else...
The switch statement is a part of JavaScript's "Conditional" Statements, which are used to perform different actions based on different conditions. Use switch to select one of many blocks of code to be executed. This is the perfect solution for long, nestedif/elsestatements. ...
} // This is the end of the if clause. else { // The optional else clause executes its code if return -x; // the comparison is false. } // Curly braces optional when 1 statement per clause. } // Note return statements nested inside if/else. ...
You can use multipleifstatements in succession like this: if (condition1) { statement1 } else if (condition2) { statement2 } else { statement3 } Below is an example: if (xhs > 25) { console.log('xhs满足大于25') } else if (xhs < 0) { ...
if (num < 0) { break; } else { sum += num; } More on JavaScript break JavaScript break With Nested Loop. When break is used inside two nested loops, it terminates the inner loop. For example, // nested for loops // outer loop for (let i = 1; i <= 3; i++) { // in...
if (cars[i] === "Saab") { continue; } text += cars[i] + ""; } Try it Yourself » Example With a label reference, skip a value in a nested loop: let text = ""; // The first for loop is labeled Loop1: Loop1: for (let i = 0; i < 3; i++) { text += i + ...
Using continue, break as well as nested if statements or other complex logic inside loops suggests, that maybe we iterate over badly filtered list and we should split it into few lists, then run them through few different functions. This encourages writing smaller functions and smaller datasets ...
This slows down the average execution time if you assume that the possible values for value are evenly distributed between 0 and 10. To minimize the number of conditions to evaluate, the code can be rewritten into a series of nested if-else statements, such as: if (value < 6){ if (...
