✨Slice, ✨Splice, and ✨Split - the three S's of string and array manipulation in Javascript! Always confused about them?
Slice: Extract a portion of a string or array with the slice() method. Pass in start and end indices to get a new substring or subarray. #programming #strings #arrays
Splice: Add or remove elements from an array with splice(). Specify the index to start at, the number of elements to remove, and any new elements to add.
Let's do a small thread on D-Branes and their charges. Before starting, let's review some familiar concepts so that it is easy to understand what follows. 1/13

In electrodynamics (using Newtonian space and time) the magnetic field is represented by a vector potential A. In order to describe the electric field, we need another scalar quantity called the scalar potential. 2/13
In special relativity, the scalar & the vector potentials can be combined into a vector potential but this potential is a four-vector. This potential which has one index is called a 1-form (or one-form). 3/13

🌟 1: All programming languages works with data, and there are 7 built in data types in #JavaScript:
• null
• undefined
• boolean
• number
• string
• object
• symbol—added in ES6!
They are also called primitive types

🌟 2: #null essentially means "no data", empty, nada. #undefined means data has not been explicitly defined or declared. #boolean evaluates to either true or false. #numbers are digits between 0-9, #strings are characters enclosed within double quotes
