The Number.isFinite() function checks if the variable is a number, but also checks if it's a finite value. Therefore, it returns false on numbers that are NaN, Infinity or -Infinity. Let's test it out on the variables we've defined above: > Number.isFinite(intVar); true > Number...
If isNaN() returns false, the value is a number.Another way is to use the typeof operator. It returns the 'number' string if you use it on a number value:typeof 1 //'number' const value = 2 typeof value //'number' So you can do a conditional check like this:const value = ...
