And the final else, if specified, is run if the previous if statements all return `false. Conditional statements are responsible to execute a piece of code depending upon some conditions. If that condition is not met, other conditions are checked using else ifs. When a condition is met, the specified code is executed. If statements are used to run code conditionally. The conditional (ternary) operator is the only JavaScript operator that takes three operands: a condition followed by a question mark ( ), then an expression to execute if the condition is truthy followed by a colon (: ), and finally the expression to execute if the condition is falsy. You can use conditional statements in your code to do this. The else statement is not executed because one of the previous if statements has already passed. This result is because the first if condition returns false ( number is not greater than or equal to 60), the second also returns false ( number is not greater than or equal to 46) but the third if statement passes and returns true ( number is greater than or equal to 40). JavaScript Conditional Execution and Variable Scope Ask Question Asked 10 years, 3 months ago Modified 10 years, 3 months ago Viewed 390 times 1 I apologize in advance, this might have been discussed on StackOverflow before, I just do not know what this is called, so I could not find a satisfactory answer. It allows for an if this, then that approach to coding, where certain actions or statements will only be executed if certain conditions are met. When you run the above, you get "number is greater than or equal to 40" printed. A javascript conditional statement is a type of programming logic that allows the code to make decisions based on conditions set by the programmer. The if/else statement is a part of JavaScript's 'Conditional' Statements, which are used to perform different actions based on different conditions. If you have a large screen, the menu will always be present on the left. ![]() If the condition is false, another block of code can be executed. Use the Menu We recommend reading this tutorial, in the sequence listed in the menu. log ( "number is greater than or equal to 60" ) } else if (number >= 46 ) The if/else statement executes a block of code if a specified condition is true.
