How to useTernary Operator in Javascript
When using the ternary operator to convert a string to a boolean, the code employs a concise one-liner. The toLowerCase()
method is applied to ensure case-insensitive comparison. The ternary operator checks if the lowercase string is equal to ‘true’. If the condition is met, it returns true
; otherwise, it returns false
.
Example: In this example, the toLowerCase()
method is used to ensure case-insensitive comparison. The ternary operator checks if the lowercase string is equal to ‘true’ and returns true
if it is, otherwise false
.
function stringToBooleanTernary(str) {
// Ternary operator: condition ? true-value : false-value
return str.toLowerCase() === 'true' ? true : false;
}
// Example usage:
const resultTernary = stringToBooleanTernary('True');
console.log(resultTernary); // Output: true
Output
true
