Sequence
This page is under construction. Please come back later.
In programming languages we have three ways to control the flow of statements: Sequence, Selection and Iteration. Sequence is the simplest and most basic flow control mechanism. It simply means that statements are executed sequentially in the order they appear in the program.
#!/usr/bin/env node; const main = async () => { let x = 1; console.log("x: " + x); x = 2; console.log("x: " + x); x = 3; console.log("x: " + x); } main().catch( e => { console.error(e) } );
Output
$ node Sequence1.js
x: 1
x: 2
x: 3
