Get empty string instead of null

Question

I have null in a row if there no number. I need to put empty string in a row instead of null.

<td>${number}</td>. // null, if there no number,

so, Am I thinking in the right way? :

!number ? number : "" 

Answer 1

This will check if the variable's type is number and if not it won't render anything:

typeof number === 'number' ? number : ''

Answer 2

try

`<td>${!number ? '' : number}</td>`

if there is no number then display '' else display number

Answer 3

You can use Nullish coalescing operator (??) that returns its right-hand side operand when its left-hand side operand is null or undefined, and otherwise returns its left-hand side operand.

Working Demo :

let number = null;

document.getElementById('numberText').innerHTML = number ?? ''

<p id="numberText"></p>
