underscore.js - Determine if all values in an array of arrays match

Question

I have an array of arrays, which looks something like this:

[[\"Some string\", \"Some other string\"],[\"Some third string\", \"some fourth string\"]]
         


        

Answer 1

My implementation with http://underscorejs.org/

/**
 * Returns true if the arrays are equal
 *
 * @param {Array} array1
 * @param {Array} array2
 * @returns {boolean}
 */
equal: function ( array1, array2 )
{
    return ( array1.length === array2.length)
        && (array1.length === _.intersection( array1, array2 ).length);
}
