Script Preparation code:

function translate(arg1, arg2) {
	return ` some text ${arg1} other text ${arg2}`;
}

const template = [' some text ', ' other text '];
function getTranslatable(arg1, arg2) {
	return {
		template: template,
		args: [arg1, arg2],
	};
}

function isEqual(t1, t2) {
	if (t1.template !== t2.template) {
		return false;
	}
	
	return t1.args.every((arg, index) => arg === t2.args[index]);
	
}

results1 = [];
results2 = [];

Tests:

build strings and compare them
const s1 = translate(1, 'foo'); const s2 = translate(1, 'foo'); results1.push(s1 !== s2);
compare declarative objects
const t1 = getTranslatable(1, 'foo'); const t2 = getTranslatable(1, 'foo'); results2.push(isEqual(t1, t2));
