You have already seen the basic structure of a JavaScript IF statement but sometimes the question you want to ask is a bit more complicated.
Greater and and less than
Rather than checking if two things are equal you can also compare which is bigger:
if (weight<targetWeight) {
If the first variable is less than the second variable the code runs. Alternatively:
if (weight<=targetWeight) {
Now the code runs if the first is less than or equal to the second. Greater than works the same way:
if (weight>=targetWeight) {
NOT
if (meat!='chicken') {
If the variable meat contains a value which is NOT equal to the string then the code runs.
Multiple checks
You can check two (or more) conditions in an IF statement:
if (meat=='chicken' && side=='chips') {
The && is saying that the first AND the second condition must be true. You can also say OR:
if (meat=='chicken' || side=='chips') {
If either of the conditions is true the code will be run.
