Local comparison causing unit test failure

Uncertain as to why this is not working properly with Dojo

doh.t(formatedValue.localeCompare("16,91 $CA") === 0, "incorrect french formatting")

The value of formattedValue is definitely "16,91 $CA" so I am certain it should be a match. However, when I attempt to include === 0 in the syntax, I receive an error stating "Binary operation argument is not assignable to type Boolean"

This is puzzling to me, as I thought this would evaluate to true or false - such as when I use formatedValue.localeCompare("56,96 $CA") === 0?

Answer №1

localeCompare is specifically used for comparing strings, not determining equality. When we talk about comparison, it means checking if one string comes before or after another string, which is commonly used for sorting purposes. However, if the goal is to simply check for equality, there are simpler ways to achieve this:

doh.t(formatedValue === "16,91 $CA", "incorrect French formatting");

or you could use:

doh.is(formatedValue, "16,91 $CA", "incorrect French formatting");
