These are super handy for decision-making. Let's see which ones we can use:
|Not equal to|
|Strict equal to|
|Strict not equal to|
|Greater than or equal to|
|Less than or equal to|
This operator is used to evaluate two values. However, they don't have to be of the same type. Meaning we can assess if a string is equal to a number!
`5` == 5; // true 5 == 5; // true
But it can also compare strings for instance:
'string' == 'string'; // true 'String' == 'string'; // false
Note: It's capital sensitive, as you can see above!
Following this is the not equal to operator, which can evaluate if a comparison is not correct.
5 != 5; // false 8 != 5; // true '8' != 5; // true 'String' != 'string'; // true 'string' != 'string'; // false
Then we have these two as strict versions, which should be preferred over the top ones. What this means is that it will check against the type as well.
5 === 5; // true '5' === 5; // false
And the same works for the not equal to strict comparison.
5 !== 5; // false 8 !== 5; // true '8' !== 5; // true
Then we have the greater than and less than operators. These can be used to assess if a value is greater or less than the compared one.
Generally, these should only be used with number values.
8 > 5; // true 8 < 5; // false 5 > 8; // false 5 < 8; // true 5 > 5; // false
We can also use the above two comparisons to check whether something hits a threshold.
We want to evaluate if a value is greater than or equal to a certain number?
5 >= 5; // true 8 >= 5; // true
Meaning our number is greater than or equal to 5, which is the case in the above example.
This can also be used for checking less than operations.
5 <= 5; // true 3 <= 5; // true
