The falsy values are false, 0, -0, 0n, "", null, undefined, and NaN.
JavaScript considers all values truthy unless they are one of a small number that are falsy. Conditional Statements if statement - use this statement if you want to execute a set of code when a condition is true if.else statement - use this. A falsy value is a value that JavaScript considers false when it encounters it in a boolean context. When creating a form, you can use webcontrols such as the check box, the radio button, the combo box, etc to handle Boolean values.Īs seen in C#, the most fundament way to formulate a conditional statement is with the if keyword.A truthy value is a value that JavaScript considers true when it encounters it in a boolean context. When creating a function, you can add a parameter to it and treat it as a Boolean value. under the directions of the programme I think either. Conditional Statements in JavaScript if statement is used to execute a set of statements based on some truthiness of a condition. if the condition is satisfied to continue running the program in a first direction, if not as the second direction. thanks conditional statement we can control program running in two directions.
Else statements: where if the same condition is false it specifies the execution for a block of code. As seen with C#, you can also assign a Boolean expression to the variable. JavaScript - Conditional statement: if, if else By conditions we can control our program. 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. In the same way, if the variable had already been declared, at any time, you can assign a Boolean value to it. It works because in JavaScript, true & expression always evaluates to expression, and false & expression always. If you want to indicate that it is Boolean, initialize it with the true or the false value. To start a Boolean value, declare a variable using the var keyword. The JavaScript language supports Boolean variables and values the same way as C#. They just have some slight differences on a couple of operators. One of the concepts that both languages share is that of conditional statements. Conditional statements execute a specific action based on the results of an outcome of true or false. Both C# and JavaScrit share the same ancestry of C-based or C-oriented languages.
