To convert a boolean to a string in TypeScript, you can use the “String constructor”, “toString()”, “template literals”, or “ternary operator”.
Method 1: Using a String constructor
The String() constructor converts a given argument to a primitive string value.
Example
let boolValue: boolean = true;
let strValue: string = String(boolValue);
console.log(boolValue)
console.log(typeof boolValue)
console.log(strValue)
console.log(typeof strValue)
Output
Method 2: Using the toString() Method
The toString() method is “used to convert a given object to its string representation.”
Syntax
booleanValue.toString()Example
let boolValue: boolean = true;
let strValue: string = boolValue.toString();
console.log(boolValue)
console.log(typeof boolValue)
console.log(strValue)
console.log(typeof strValue)
Output
Method 3: Using the template literals
You can use the template literals by wrapping your content inside backticks (` `) instead of single or double quotes. You can use `${expression}` within the template literals to evaluate JavaScript/TypeScript expressions.
Example
let boolValue: boolean = true;
let strValue: string = `${boolValue}`;
console.log(boolValue)
console.log(typeof boolValue)
console.log(strValue)
console.log(typeof strValue)
Output
Method 4: Using the ternary operator
The ternary operator (conditional operator) is “used to convert a boolean to a string value based on its truthiness.”
Syntax
condition ? valueIfTrue : valueIfFalseExample
let boolValue: boolean = true;
let strValue: string = boolValue ? 'true' : 'false'
console.log(boolValue)
console.log(typeof boolValue)
console.log(strValue)
console.log(typeof strValue)Output
This approach is more verbose than the previous ones, but it can be helpful in scenarios where you want to be explicit about the conversion or if you want to provide custom string values for true and false.
That’s it!
