TypeScript: Convert a bool to string value

Question

I am unable to convert a boolean to a string value in TypeScript.

I have tried to use the toString() method but it does not seem to be implemented on bool.

Answer 1

Updated for comments!

You can now use toString() to get a string value from a boolean type.

var myBool: boolean = true;
var myString: string = myBool.toString();
console.log(myString);

This outputs:

"true"

And has no errors or warnings.

Answer 2

For those looking for an alternative, another way to go about this is to use a template literal like the following:

const booleanVal = true;
const stringBoolean = `${booleanVal}`;

The real strength in this comes if you don't know for sure that you are getting a boolean value. Although in this question we know it is a boolean, thats not always the case, even in TypeScript(if not fully taken advantage of).

Answer 3

One approach is to use the Ternary operator:

myString = myBool? "true":"false";

Answer 4

return Boolean(b) ? 'true':'false'

Answer 5

This if you have to handle null values too:

stringVar = boolVar===null? "null" : (boolVar?"true":"false");

Answer 6

if you know your value is always true/false, you can use JSON.stringify(myBool) it will give you value like 'true' or 'false'
