The values read-only property of the CSSMathProduct interface returns a CSSNumericArray containing the CSSNumericValue objects being multiplied together.
The following code creates a CSSMathProduct object and logs its values and length.
const product = new CSSMathProduct(CSS.px(10), CSS.percent(50));
console.log(product.values);
// CSSNumericArray {0: CSSUnitValue, 1: CSSUnitValue, length: 2}
console.log(product.values.length); // 2We then iterate over the values, logging their type, value, unit, and stringified text. Each of these matches the CSSNumericValue objects that were passed into the constructor (or the terms of the multiplication/division it represents), in the same order.
for (const value of product.values) {
console.log(
`${value.constructor.name}: ${value.value} ${value.unit} (${value})`,
);
}
// CSSUnitValue: 10 px (10px)
// CSSUnitValue: 50 percent (50%)
