Numerical string to number convert
// "1.2" -> 1.2
console.assert(convert('1.2') === 1.2)
// " " -> " " (not a number)
console.assert(isNaN(convert(' ')))

// "12a" -> "12a" (not a number)
console.assert(convert('12a') === '12a')
console.assert(isNaN(convert('12a')))
// null -> null (not a number)
console.assert(convert(null) === null)
