how to use the parseint function from lodash in javascript

parseInt is a native JavaScript function that parses a string argument and returns an integer of the specified radix (the base in mathematical numeral systems). Lodash provides a variation of the parseInt function that has some additional features. In order to use the parseInt function from Lodash, you need to first import it into your code, if you haven't already:

index.tsx
const _ = require('lodash');
29 chars
2 lines

Once you have imported Lodash, you can use the parseInt function by calling it on the _ object and passing in the string you want to parse as the first argument:

index.tsx
const num = _.parseInt('123');
console.log(num); // output: 123
64 chars
3 lines

The second argument to the Lodash parseInt function is the radix. Unlike the native JavaScript parseInt, the Lodash parseInt function will automatically infer the radix from the string argument if it is not specified. However, if you want to specify the radix explicitly, you can do so by passing it as the second argument:

index.tsx
const num = _.parseInt('010101', 2);
console.log(num); // output: 21
69 chars
3 lines

In this example, we explicitly set the radix to 2, which indicates that the string '010101' should be interpreted as a binary number. The resulting integer value is 21.

Overall, the Lodash parseInt function provides a convenient and flexible way to parse strings into integers in JavaScript.
