Learn JavaScript on the Now Platform: Lesson 4 - Simple Arithmetic Operators

This lesson covers some simple arithmetic operators to help you understand how to add, subtract, mulitply, divide, and modulo (the remainder of division). I also include some time saving shortcuts you won't want to miss.

Love this guy!

Best instructor EVER! Thank you so much Chuck.

Great stuff, was not aware of Parenthesis usage in relation to mathematical order of processing.

Increment of a (a++) cannot be stored in variable? ex: var a =12; var b = 3; var c = a++; then print c, the output is 12 instead 13.

I have run into a big problem when trying to add a value (disk size) in a flow designer "for each" logic.
How do I get this to work: "var disk_bytes = disk_bytes +
Return disk_bytes"
It is in a for each logic ;-)

Hi Chuck, one more question please, i have 2 variables var a = 10, var b= 10, i did gs.info(a + b) and i got 1010 as javascript takes var as string by default, but when you did var a = 12 and when you performed gs.info(a + 2) why is it taking a as integer and giving 14?

I love your videos but it would be a bit better to add why we would be using this. What is the overall goal?

[theredpill]

Ohh goodness. I dont know if I can learn college algebra and this at the same time...

Would you please explain what is happening here? When I run the scripts, I get a slightly different result. For example, when Chuck runs the script:

// Assignment
var a = 12;
var b = 3:

// Addition
gs.info(2 + 2);
gs.info(a + 2);

He gets: *** Script: 4

However, I get:
x_859663_k_s_first: 4
x_859663_k_s_first: 14

Case:01
a = 1
b = 1
gs.info((++a + b++)*2);

Output: 6 (why not 8 😬? )

Case:02
Though this will return 8

a = 1
b = 1
b++
gs.info((++a + b)*2);

And here is 4 ? 🤔
a = 1
b = 1
b - -
gs.info((++a + b++)*2);

takeaway from LS04 - nothing can take over parenthesis. Thanks!
