Hello everyone. I am finishing up my Calculator app, and I’m wondering how should I approach problem of evaluating equations. Everything other is in place: writing digits, operators, brackets and decimals work fine.
How should I approach evaluation of equation? My app writes equations as a string. I’ve looked up eval() function, but learned that it’s very unsafe and should not be used.
BUT, there is other simple alternative - using new Function.
let operation = "2 * 5 + 10" let evaluation = Function("return " + operation)() console.log(evaluation) // logs correct result: 20
What do you think about Function method? Is it safer than eval(), or should I write my own way from scratch?
