JS Reminder2 String concatenation, operators

1. String concatenation

This is something that looks basic but easy to forget. let’s review

String concatenation

line 1: ‘my’ + ‘ cat’ = my cat

line 2: ‘1’ + 2 = 12, (when string + number, number will be changed to string)

line 3 : `string literals: 1+ 2 = ${1 + 2}`(use ${} inside of backtic)

when you want to print youngmin’s book on the console.

‘youngmin’s book’ → it is wrong. it will not be printed.

How do I print youngmin’s book on console? see below

use back slush

console.log(‘youngmin\’s book’) → it will be printed youngmin’s book on the console.

2. Numeric operators
