Example of Using Nested If Statements Conclusion The if Statement in JavaScript Let us start this guide off with the most basic conditional statement that you should learn, the if statement. The JavaScript if statement allows you to run a code block when the condition you specify is true. Belo...
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...
let nestedIfElseHell = (str) => { if (typeof str == "string"){ if (str.length > 1) { return str.slice(0,-1) } else { return null } } else { return null } } nestedIfElseHell("") // => null nestedIfElseHell("h") // => null nestedIfElseHell("hello!") // => "...
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 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 (...
if (document.form1.threeChar.value.length == 3) { return true; } else { alert("Enter exactly three characters. " + document.form1.threeChar.value + " is not valid."); return false; } } 「switch 语句节」switch 语句允许一个程序求一个表达式的值并且尝试去匹配表达式的值到一个 case 标...
JavaScript statements are commands to the browserJavaScript code is a sequence of statementsJavaScript statements are separated with semicolonMultiple statement on one line is allowedJavaScript statements can be grouped together in code blocksYou can break a code line after an operator or a comma. ...
