Returns true or false.\n\n**everyeven** takes a parameter such as cell range (e.g. `everyeven(a1,a2)`).  Returns true or false.\n\n**firsttwo** takes a parameter such as cell range (e.g. `firsttwo(a1,a2)`).  Returns the first two items in the list (e.g. `firsttwo(4,9,5)` returns `4,9`).\n\n**lasttwo** takes a parameter such as cell range (e.g. `lasttwo(a1,a2)`).  Returns the last two items in the list (e.g. `lasttwo(4,9,5)` returns `9,5`).\n\n**has2** takes a parameter such as cell reference or number (e.g. `has2(a1)` or `has2(a17,f17)`).  Checks if 2 is included.  Returns true or false.\n\n**increment** takes a parameter such as cell range or number (e.g. `increment(a2)` or `increment(4)`).  Adds 1.  For example, `increment(4)` returns `5`.\n\n**random** takes two parameters such as cell references (e.g. `random(a17,b17)`).  Returns the random number between the first two numbers.\n\n**range** takes two parameters - `start` and `end`.  These parameters can be cell references or numbers.  Gives a list of numbers within the `start` and `end`.  For example, `range(4,6)` returns `4,5,6`.\n\n**nodupes** takes a parameter such as cell range (e.g. `nodupes(a12,b12)`).  Removes duplicates.  For example, `nodupes(4,5,4,2)` returns `4,5,2`.\n\nNote that cell ranges do not have to be consecutive.  For example, you can use `sum(a1,a5,a9)`\n\nGo to any cell (e.g. A3), type `=` followed by the function name (e.g. even) and its cell reference (e.g. A3) or number.  Then press `Enter`.  For example, `=sum(a1,b1)`\n\nSeparate the cell ranges or numbers by commas (e.g. `a1,a2,a3,a4,a5`, `15,19,11`).  For example, `sum(4,5,3)` or `sum(a1,b1,c1)`.\n\nYou can also do addition, multiplication, subtraction and division.  Type `=` followed by expression (e.g. `3+8`).  Then press enter.  For example, `=3+8`.\n\nYou can also nest functions (e.g. `sum(range(4,10))`, which returns `49`).\n\n## Technologies\n\nUses HTML5, CSS3 and JavaScript.  Covers concepts like the `map()` method, `find()` method, `parseInt()` method and the `includes()` method.\n\n## Deployment\n\nDeployed on [GitHub Pages](https://derektypist.github.io/build-a-spreadsheet/) using the main branch.\n\n## Credits\n\n### Acknowledgements\n\n[FreeCodeCamp - JavaScript Algorithms and Data Structures](https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures-v8/)\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fderektypist%2Fbuild-a-spreadsheet","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fderektypist%2Fbuild-a-spreadsheet","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fderektypist%2Fbuild-a-spreadsheet/lists"}
