What is tzlib ?
It provides extension methods on javascript Array.
Some methods are replica of linq in .Net (C#).
Function Documentation :
first()
Returns first elements of an array.
function first() { let numArray = new Array<number>(); numArray.push(3); numArray.push(100); numArray.push(2); numArray.push(10); numArray.push(4); console.log(numArray.first()); // This will print 3
}
### *last()*
___
> Returns last elements of an array.
```javascript
function last() {
let numArray = new Array<number>();
numArray.push(3);
numArray.push(100);
numArray.push(2);
numArray.push(10);
numArray.push(4);
console.log(numArray.last()); // This will print 4
}
clear()
Remove all elements from an array.
function clear() { let numArray = new Array<number>(); numArray.push(3); numArray.push(100); numArray.push(2); numArray.push(10); numArray.push(4); console.log(numArray.clear()); // This will print []
}
### *where(predicate)*
___
> Returns subset of source Array that satisfies predicate.
```javascript
function where() {
let numArray = new Array<number>();
numArray.push(3);
numArray.push(100);
numArray.push(2);
numArray.push(10);
numArray.push(4);
console.log(numArray.where(ele => ele > 10)); // This will print 100
console.log(numArray.where(ele => ele === 3)); // This will print 3
}
addRange()
Returns Array which is superset of two arrays.
function addRange() { let numArray = new Array<number>(); numArray.push(3); numArray.push(100); numArray.push(2); numArray.push(10); numArray.push(4);
const augArray = [5,6,];
console.log(numArray.addRange(augArray)); // This will print 3,100,2,10,4,5,6
}
### *removeRange()*
___
> Returns first elements of an array.
```javascript
function removeRange() {
let numArray = new Array<number>();
numArray.push(3);
numArray.push(100);
numArray.push(2);
numArray.push(10);
numArray.push(4);
console.log(numArray.removeRange(2,2)); // This will print 2,10
}
strictSort()
Sorts array for both number & String.
function strictSort() { let sArray = new Array<number>(); sArray.push('IronMan'); sArray.push('Thor'); sArray.push('Captain America'); sArray.push('Hulk');
console.log(numArray.strictSort);
// This will print : Captain America, Hulk, IronMan, Thor
let numArray = new Array(); numArray.push(3); numArray.push(100); numArray.push(2); numArray.push(10); numArray.push(4);
console.log(numArray.strictSort);
// This will print : 2,3,4,10,100
}
### *orderBy(property,sortOrder?)*
___
> Returns sorted Array of objects determined by key.
> User has an option to select either asceding or descending order.
```javascript
function orderBy(expression,sortOrder) {
let sArray = new Array<number>();
sArray= [{ Name: 'Tony Stark', Alias: 'Iron Man' }, { Name: 'Robert Bruce Banner', Alias: 'Hulk' },
{ Name: 'Steve Rojer', Alias: 'Captain America' }, { Name: 'Natasha Romanova', Alias: 'Black Widow' }];
console.log(numArray.orderBy(item=>item.Name)); // Will sort array by Name property in Asc order
console.log(numArray.orderBy(item=>item.Alias),false); // Will sort array by Alias property in Desc order
}
insertAt(item,position)
Insert element at mentioned position.
function insertAt() { let numArray = new Array<number>(); numArray.push(3); numArray.push(100); numArray.push(2); numArray.push(10); numArray.push(4);
console.log(numArray.insertAt(50,0,1)); // Will insert 50 at array index 1, print 3, 50, 100, 2, 10, 4 }
### *getMatchCount(predicate)*
___
> Returns count of number of matching element.
```javascript
function getcount() {
let numArray = new Array<number>();
numArray.push(3);
numArray.push(100);
numArray.push(3);
numArray.push(10);
numArray.push(2);
console.log(numArray.getMatchCount(ele=>ele===3)); // Will return 2.
}
