I am actually following a course of javascript and came across a piece of code where he say if true then do {} but what is true not specifically explained
//scope.js
let a = 'JavaScript' // is a global scope it will be found anywhere in this file
let b = 10 // is a global scope it will be found anywhere in this file
function letsLearnScope() {
console.log(a, b) // JavaScript 10, accessible
if (true) {
let a = 'Python'
let b = 100
console.log(a, b) // Python 100
}
console.log(a, b)
}
letsLearnScope()
console.log(a, b) // JavaScript 10, accessibleThe issue is this code working fine not giving error my question what true he is talking about
