Use JavaScript operators like if or the conditional operator to create. And the final else, if specified, is run if the previous if statements all return `false. Conditional rendering in React works the same way conditions work in JavaScript. 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. If you have a short condition and want to do it in one line, the ternary operator will be perfect. There are multiple different types of conditionals in JavaScript including: If statements: where if a condition is true it is used to specify execution for a block of code. One of the main advantages of using it is to write shorthand if else statements. Conditional statements control behavior in JavaScript and determine whether or not pieces of code can run. The else statement is not executed because one of the previous if statements has already passed. In summary, the conditional operator in JavaScript is powerful, but you should use it with precaution. 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). In another case, if you have only if condition you can use & operator as: condition & action For instance:ttings & (ttings new TableSettings()) FYI: You have to try to avoid using if-else or at least decrease using it and try to replace it with Polymorphism or Inheritance. switch statement - use this statement if you want to select one of many sets of lines to execute. if.else statement - use this statement if you want to select one of two sets of lines to execute. When you run the above, you get "number is greater than or equal to 40" printed. In JavaScript we have three conditional statements: if statement - use this statement if you want to execute a set of code when a condition is true. log ( "number is greater than or equal to 60" ) } else if (number >= 46 ) Since the operator performs based on the conditions of the expressions, it is called the conditional operator in JavaScript.
