How does lodash.toNumber work?

lodash.toNumber is a method that converts a given value to a number, which can be either a string or any other data type, by parsing it with parseFloat(), but also supports hexadecimal, binary, and octal literals. If the given value is not a valid number, it returns NaN.

const _ = require("lodash");

console.log(_.toNumber("42")); // Output: 42
console.log(_.toNumber("3.14")); // Output: 3.14
console.log(_.toNumber("not a number")); // Output: NaN
console.log(_.toNumber(null)); // Output: 0
console.log(_.toNumber(undefined)); // Output: NaN
console.log(_.toNumber("")); // Output: 0

In this example, lodash.toNumber is used to convert a string representation of a number to a number. It also handles edge cases such as converting null to 0, undefined to NaN, and an empty string to 0.
