My JavaScript code needs to be converted to TypeScript for proper functionality.
categoryAxis.renderer.labels.template.adapter.add("dy", function(dy, target) {
if (target.dataItem && target.dataItem.index % 2 === 0) {
return dy + 25;
}
return dy;
});
The error is occurring on 2 == 2.
If you are using the following JavaScript code:
target.dataItem && target.dataItem.index & 2 == 2
It is equivalent to:
target.dataItem && target.dataItem.index & (2 == 2)
target.dataItem && target.dataItem.index & true
JavaScript automatically coerces true as 1, but TypeScript does not do this implicitly.
So if you write:
target.dataItem && target.dataItem.index & 1
or
target.dataItem && target.dataItem.index & +true
In TypeScript, it compiles and behaves the same way as your original JavaScript code.
If your JavaScript code was incorrect from the start, other answers have provided multiple suggestions for corrections.
It appears that typescript evaluates 2 == 2 first, resulting in true, and then incorrectly evaluates target.dataItem.index & true. To correct this, consider adding parentheses:
(target.dataItem.index & 2) == 2It seems like the issue lies with target.dataItem.index & 2, perhaps what you intended was to use double ampersands instead: target.dataItem.index && 2
