A lightweight Javascript Library that extends Javascript's array functionalities.
Just import arrayExt.js file from the package folder into your project and arrays will automatically have new functions. Or you can use it in your node server installing the arrayext.js package (npm install arrayext.js) - https://npmjs.org/package/arrayext.js
### index(value, comparisonFunction) Returns the position of the value in the array and -1 if it doesn't exists, it accepts an optional comparison function as a parameter to check the valueUsage:
var foo1 = [{a: 1, b: 2}, {a: 3, b: 4}];
var foo2 = [1,2,3,4];
var check = function(elem, value) { /* elem is the array element and value the value we send */
return elem.a === value;
};
foo1.index(3, check); /* Returns 1 */
foo1.index(8, check); /* Returns -1 */
foo2.index(3); /* Returns 2 */
Usage:
var foo1 = [1,3,5,7,9];
var foo2 = [1,3,5,7,9];
var check = function(elem1, elem2){ /* elem1 is the array element and elem2 the element of the array we send */
return elem1 === elem2;
};
foo1.same(foo2); /* Returns true*/
foo1.same(foo2, check); /* Returns true*/
foo2.push(2);
foo1.same(foo2); /* Returns false*/
foo1.same(foo2, check); /* Returns false*/
Usage:
var foo1 = [1,3,5,7,9];
var foo2 = [1,3,5];
var foo3 = [1,6];
var check = function(elem1, elem2){ /* elem1 is the array element and elem2 the element of the array we send */
return elem1 === elem2;
};
foo1.hasList(foo2); /* Returns true*/
foo1.hasList(foo2, check); /* Returns true*/
foo1.hasList(foo3); /* Returns false*/
Usage:
var foo1 = [1,3,5,7];
var foo2 = foo1.copy();
foo1 == foo2 /* Returns false */
Usage:
var foo = [2,4,6,8,0];
foo.sublist(1,3); /* Returns [4, 6, 8]*/
Usage:
var foo = [1,3,5,7];
foo.shove(9); /* Returns 5 and foo is [1,3,5,9] */
foo.shove(9); /* Returns 5 and foo is [1,3,5,9] */
/* With comparison function */
var foo = [{a: 1, b: 2}];
var check = function(elem, value) { /* elem is the array element and value the value we send */
return elem.a === value.a;
};
foo.shove({a:3, b:4}, check); /* Returns 2 and foo is [{a: 1, b: 2}, {a:3, b:4}] */
foo.shove({a:3, b:4}, check): /* Returns 2 and foo is [{a: 1, b: 2}, {a:3, b:4}] */
Usage:
var foo = [1,5,9];
foo.insert(3,2)); /* Returns 4 and foo is [1,5,3,9] */
Usage:
var foo = [1,3,5,7,9];
foo.remove(3)); /* Returns 4 and foo is [1,5,3,9] */
Usage:
var foo = [0,1,2,null,"hello",""];
foo.clean(); /* foo is [0,1,2,"hello"] */
Usage:
var foo1 = [1,3,5,7,9];
var foo2 = [1,2,5,6,9];
foo1.intersection(foo2); /* Returns [1,5,9] */
var foo3 = [{a: 1, b:2}, {a: 3, b: 4}];
var foo4 = [{a: 1, b:2}];
var check = function(elem1, elem2){ /* elem1 is the array element and elem2 the element of the array we send */
elem1.a == elem2.a
};
foo3.intersection(foo4, check); /* Returns [{a: 1, b:2}] */
Usage:
var foo1 = [1,3,5,7,9];
var foo2 = [5,9];
foo1.deduct(foo2); /* Returns [1,3,7] */
var foo3 = [{a: 1, b:2}, {a: 3, b: 4}];
var foo4 = [{a: 1, b:2}];
var check = function(elem1, elem2){ /* elem1 is the array element and elem2 the element of the array we send */
elem1.a == elem2.a
};
foo3.deduct(foo4, check); /* Returns [{a: 3, b:4}] */
Usage:
var foo1 = [1,3,5,7,9];
var foo2 = [2,4,5,6,8,9];
foo1.merge(foo2); /* Returns [1,3,5,7,9,2,4,6,8] */
var foo3 = [{a: 1, b:2}, {a: 3, b: 4}];
var foo4 = [{a: 1, b:2}, {a: 5, b:6}];
var check = function(elem1, elem2){ /* elem1 is the array element and elem2 the element of the array we send */
elem1.a == elem2.a
};
foo3.merge(foo4, check); /* Returns [{a: 1, b:2}, {a: 3, b:4}, {a: 5, b:6}] */
