In JavaScript, a (non-template) string can be written with either single or double quotes. For example:
'Hello'"Hello".Personally, we prefer double quotes! It's important to have styling conventions so that all the code in a project looks consistent, making it easier to read and contribute to.
Square brackets are used to access individual characters inside a string. The characters are numbered from 0 to length-1. It's similar to how strings and lists work in Python, Go and many other languages.
const greeting = "Hello";
greeting[0]; // 'H'
greeting[1]; // 'e'
greeting[2]; // 'l'
greeting[3]; // 'l'
greeting[4]; // 'o'
// you can also get the last char at length-1
greeting[greeting.length - 1]; // 'o'
The .length property is used to get the number of characters in a string.
