• All numbers will be whole.
• All numbers will be positive.

function stringInt(str) {return parseInt(str);
}

TestCases

let Test = (function(){return {assertEquals:function(actual,expected){if(actual !== expected){let errorMsg = `actual is ${actual},${expected} is expected`;throw new Error(errorMsg);}},assertSimilar:function(actual,expected){if(actual.length != expected.length){throw new Error(`length is not equals, ${actual},${expected}`);}for(let a of actual){if(!expected.includes(a)){throw new Error(`missing ${a}`);}}}}
})();
Test.assertEquals(stringInt("6"), 6)
Test.assertEquals(stringInt("2"), 2)
Test.assertEquals(stringInt("10"), 10)
Test.assertEquals(stringInt("666"), 666)
