Unexpected string concatenation
16 return elements.map((element) => {
17 const olFeature = element.getOlFeature();
18 const sig = olFeature.get('sig');
19 const sk: string = sig.kat ? 'sign' + capitalizeFirstLetter(sig.kat) : 'csvGroupArea';20 const geometry = element.getOlFeature().getGeometry();
21 const extent = geometry?.getExtent();
22 const centroid = availableProjections[0].translate(extent ? getCenter(extent) : []);
Description
In ES2015 (ES6), we can use template literals instead of string concatenation.
var str = `Hello, ${name}!`;
Bad Practice
var str = "Hello, " + name + "!";
var str = "Time: " + (12 * 60 * 60 * 1000);
Recommended
var str = "Hello World!";
var str = `Hello, ${name}!`;
var str = `Time: ${12 * 60 * 60 * 1000}`;
var str = "Hello, " + "World!";
