According to the syntax structure we gave you above, you can now easily distinguish that we have first declared and initialized the variable with the value 1. We have set the condition, which in our case is to not count odd numbers greater than 10, and the final one is the pace, and ...
Here's the syntax in terms of code: for (initialization; condition; update) statement; The pair of parentheses following the for keyword consists of three different configurations, each separated by a semicolon (;). initialization— here any variables to be used in the loop are initialized to...

Expression 1 sets a variable before the loop starts (let i = 0). Expression 2 defines the condition for the loop to run (i must be less than 5). Expression 3 increases a value (i++) each time the code block in the loop has been executed. ...
for/oflets you loop over data structures that are iterable such as Arrays, Strings, Maps, NodeLists, and more. Thefor/ofloop has the following syntax: for(variableofiterable) { //code block to be executed } variable- For every iteration the value of the next property is assigned to the...

The spread operator has the same syntax as the rest parameter, but the spread operator takes the Array itself and not just the arguments. We can use the Spread parameter to get the values of an Array, instead of using a for loop or any other method. ...
