![]() ![]() Hope you like the tutorial and find this informative. Let booleanValue = getBoolean(stringValue) //returns trueĬonsole.log(booleanValue) Output false Conclusion If you want to convert string to boolean in JavaScript by using the switch case then below is the code for this. We can also achieve it by using the switch case statement. Let booleanValue = stringValue.toLowerCase() = 'true' ? true : false Ĭonsole.log(booleanValue) Output true 5. Here we simply check the string for its equality with ‘true’ and return a boolean value true if there is a match and false otherwise by making use of the ternary operator. By using the ternary operator we can achieve it easily and our code loops are much more readable. This is one of the easiest ways to convert string to boolean in JavaScript. Let booleanValue = JSON.parse(stringValue) //returns trueĬonsole.log(booleanValue) Output true 4. If the string value is ‘true’ then it is converted to a boolean object with value as true and otherwise it is converted into the object with a false value. This method parses a string as JSON and converts it into an object corresponding to the given text. This is one of the most used methods in web applications based on JavaScript. Use JSON.parse() in JavaScript to Convert String to BooleanĪnother way to convert string to boolean in javascript is by using JSON.parse() method. If the string has the value ‘true’, then the boolean value will also be true otherwise it has a false value. Here we have used the = operator to check the string value against the ‘true’ in string format. Let booleanValue = (stringValue = "true") //returns true It returns the value true if both the operands have the same value and returns false if the value does not match. ![]() double equal sign = which compares the values of the operands on its right and left-hand side. We can also make use of a comparison operator i.e. We used /i at the end of the regular expression for case insensitive matching. Let booleanValue = (/true/i).test(stringValue) //trueĬonsole.log(booleanValue) Output true string to boolean in Javascript by using a test() method If the string contains the value ‘true’, then it gives us boolean value true else it gives false. In this case, we simply check whether the string contains true or not. The test()method of Javascript will match a regular expression against a given string. Use test() Method to Convert String to Boolean Javascript We will demonstrate 5 different ways to convert string to boolean in Javascript with the help of an example. checkbox) value which is stored as a string in the database and based on this value we want to perform our logic on the UI i.e. Overviewįirst, an important question arises where does its practical usage come into the picture? Its practical application is when we have check conditions ( i.e. We may have a boolean value in string format in some cases and we want its equivalent value such as true or false. In this tutorial, we will learn how we can convert the string to boolean in Javascript. ![]()
