Simplifying JavaScript Using Conditionals

This article will describe a few simple ways to condense and simplify your JavaScript code.

Did you know that SuiteScript (NetSuite programing language) is built off of JavaScript?

Simple “AND”, “OR” check

• You can use “&&” to conditionally run a line of code:

let x = 5;
let y = 0;
y > 0 && x = x + 1; 

In this example, the x = x + 1 part will not execute since y > 0 is false. You can use this method to remove “if” statements and shrink your code base.

• You can use “||” to conditionally run a line of code. This is similar to the above but is used much less often.

“In-line if/else” statement

Use this to write condensed and convenient if/else statements

let x = 5;
let y = 0;
z = (x + y > 3) ? 6 : 7;

The syntax is as follows: “conditional” ? code to execute if conditional is true : code to execute if conditional is false

This statement is a really handy tool to cut down on your code base and can be easy to read once you get used to it.
