I would like to create an npm package for common functions that I use and are not part of javascript , but I dont know how can I create them to use them as methods, let me explain myself
For example I want to use a function like
let reverseString = (string) => string.split('').reverse().join('');
For sure I could use it like reverseString(''somethinghere')
But I would like to use it like 'somethinghere'.reverseString()
Thank you so much in advance.....
Oh. Its not at all related to npm package. You are talking about JS prototypes. Basically you want to add custom function in String class. Not a good idea to do but still if you want you can do
String.prototype.reverseString = function (str) {
return str.split('').reverse().join('');
}
Create a .js file with your method:
module.exports = {
reverseString: (string) => string.split('').reverse().join('')
}
Then elsewhere, use it with require()
const somethinghere = require('myfile.js')
somethinghere.reverseString('hello')
