Understanding Equals - Single, Double, or Triple Equals?
Показать описание
This tutorial will teach you the difference between single, double, and triple equals, for beginners.
In a nutshell:
Single-equals (=) are used to define values.
Double-equals (==), used without a space in the middle, are used to compare two values in a conditional statement (if)
Triple-equals (===), still no spaces, are used to compare two values with TYPE in mind. So a string containing just "5" will not equal an integer of just 5, whereas a double-equals would return they would.
If you have any questions, please post them below. Also, if you have any suggestions for future tutorials, please post those as well!
