interface node {

index: number;

}

//base class which hold's array of nodes inside data array

class Search {

public data: Array<any> = new Array();

constructor() { };

}

//extend Search class

class LinearSearch extends Search {

constructor(_data: Array<any>) {

super();

this.data = _data;

}

public search(_value) {

for (var i = 0; i < this.data.length; i++) {

if (this.data[i] === _value) {

return { index: i, value: this.data[i] };

}

}

}

}

var linearSearch = new LinearSearch([4, 5, 11, 23, 12]);
