The modulo function is the integer remainder of dividing var1 by var2.
The modulus operator returns the first operand modulo the second operand, that is, var1 modulo var2, in the preceding statement, where var1 and var2 are variables. .
A strict comparison (e.
let x = 5; let y = 3; let z = (x + y) * 2; // z is 16. Example 4: UNION with DISTINCT. It returns an array of information or null on a mismatch.
. Function names can contain letters, digits, underscores, and dollar signs (same rules as variables). . Practical examples and use cases. Operators take one or more operands and are capable of manipulating target values or operands.
. let x = 5; let y = 3; let z = (x + y) * 2; // z is 16.
In this example, the spread operator is used to create a new object merged that contains all the properties from obj1 and obj2.
