13. Elaborate on the IF function in Excel. Excel’s IF function enables you to run logical tests and return various values depending on the outcome. You can use your spreadsheet to execute conditional computations and make judgments thanks to it. Syntax: IF(logical_test, value_if_true, value...
There are different memory areas allocated by JVM such as Heap, Stack, Method Area,PC Registers, and Native Method Stack. If I run outof parade with zero args on the command line, the value stored in the String array passed into the main() method is blank or NULL? The Stringarray will...
If the array is highly nested we can directly pass ‘Infinity’ to flatten the complete array at once. Example – const arr = [1, [2, [3, [4, [5]]]; console.log(arr.flat(Infinity)); Output – [1,2,3,4,5] 12. What are higher-order functions in JavaScript? Higher order...
Java Runtime Environment (JRE) is the implementation of JVM. JRE consists of JVM and java binaries and other classes to execute any program successfully. JRE doesn’t contain any development tools like java compiler, debugger, etc. If you want to execute any java program, you should have JRE...
