how is push used in javascript code example

Example 1: pushing to an array

Example 2: javascript add items to array

//adding items to array
objects = [];
objects.push("you can add a string,number,boolean,etc");
//if you more stuff in a array
//before i made a error doing value = : value
objects.push({variable1 : value, variable2 : value);
