What's the meaning and how to use x += 5; ?

I have been seeing this on challanges but still not sure what it actually means... Can someone explain. Thank you šŸ˜Š

Jarred Lazarus Suppose you had an int variable, sum, and you wanted to add 10 to it. How would you do this? Here's one solution : sum = sum + 10; This kind of operation is very common (where 10 is replaced by whatever value you want). //OR You can use the compound addition assignment operator, which looks like: += (plus sign, followed by equal sign). sum += 10; // Add 10 to sum Suppose, instead of adding a value to sum, you wanted to double it? That is, you wanted to multiply it by 2? One way to do this is : sum = sum * 2; // Multiply sum by 2 //OR sum *= 2; // Multiply sum by 2 Read the comments in the lessons as you can find a great examples and explanations. šŸ‘ ā€¢ https://www.sololearn.com/learn/JavaScript/1131/

ā€¢Simple to understand => var x ; x+=5;//x is undefined and x is initializing to 5 ā€¢Easy to learn => x+=5;//x=x+5; x=5;//x=0+5; ā€¢In-practical => x=undefined;//x is undefined x=x+5;//x is initializing and adding to 5 Where x = 5; //x is initialize to 5;

x+=5 is logically same as x=x+5 { if x=2 then x+=5 equals to 7 } but it's better practice to write it this way. i hope you got it.

Example: int x=5; x+=5 <-------> x=x+5 x=5+5 =10 Both are same

x+=5 simply means x = x + 5 Same case applies to all the other mathematical operations. i.e x-=5 means x = x - 5 x/=5 means x = x / 5 x*5 means x = x * 5
