How to convert string with mathematical expression?

Question

JavaScript

Okay, the bottom line is this: there is an array. It contains, for example, the following lines: "1 + 1 = 2", "2 - 1 = 5", "4 * 4 = 16". And it would be necessary to somehow compare the string with true / false. If you take and stupidly compare, then it produces false, regardless of whether the expression is correct, but this is predictable. How to solve my problem? Thank you. And sorry for the noobness, I just recently took up JS.

Answer 1

function runTest(str) {
  var args = str.split('=');
  return (new Function('', 'return ' + args[0] + '===' + args[1] +';'))();
}

runTest('4 * 4 = 16');  //true

Answer 2

Try to split the string through = and pass the resulting 2 pieces to the eval function. And compare the results
